1. INTRODUCTION

This memo documents the process currently used by the Internet

community for the standardization of protocols and procedures. The

Internet Standards process is an activity of the Internet Society

that is organized and managed on behalf of the Internet community by

the Internet Architecture Board (IAB) and the Internet Engineering

Steering Group (IESG).

1.1 Internet Standards

The Internet, a loosely-organized international collaboration of

autonomous, interconnected networks, supports host-to-host

communication through voluntary adherence to open protocols and

procedures defined by Internet Standards. There are also many

isolated interconnected networks, which are not connected to the

global Internet but use the Internet Standards.

The Internet Standards Process described in this document is

concerned with all protocols, procedures, and conventions that are

used in or by the Internet, whether or not they are part of the

TCP/IP protocol suite. In the case of protocols developed and/or

standardized by non-Internet organizations, however, the Internet

Standards Process normally applies to the application of the protocol

or procedure in the Internet context, not to the specification of the

protocol itself.

In general, an Internet Standard is a specification that is stable

and well-understood, is technically competent, has multiple,

independent, and interoperable implementations with substantial

operational experience, enjoys significant public support, and is

recognizably useful in some or all parts of the Internet.

1.2 The Internet Standards Process

In outline, the process of creating an Internet Standard is

straightforward: a specification undergoes a period of development

and several iterations of review by the Internet community and

revision based upon experience, is adopted as a Standard by the

appropriate body (see below), and is published. In practice, the

process is more complicated, due to (1) the difficulty of creating

specifications of high technical quality; (2) the need to consider

the interests of all of the affected parties; (3) the importance of

establishing widespread community consensus; and (4) the difficulty

of evaluating the utility of a particular specification for the

Internet community.

The goals of the Internet Standards Process are:

o technical Excellence;

o prior implementation and testing;

o clear, concise, and easily understood documentation;

o openness and fairness; and

o timeliness.

The procedures described in this document are designed to be fair,

open, and objective; to reflect existing (proven) practice; and to

be flexible.

o These procedures are intended to provide a fair, open, and

objective basis for developing, evaluating, and adopting Internet

Standards. They provide ample opportunity for participation and

comment by all interested parties. At each stage of the

standardization process, a specification is repeatedly discussed

and its merits debated in open meetings and/or public electronic

mailing lists, and it is made available for review via world-wide

on-line Directories.

o These procedures are explicitly aimed at recognizing and adopting

generally-accepted practices. Thus, a candidate specification

must be implemented and tested for correct operation and

interoperability by multiple independent parties and utilized in

increasingly demanding environments, before it can be adopted as

an Internet Standard.

o These procedures provide a great deal of flexibility to adapt to

the wide variety of circumstances that occur in the

standardization process. Experience has shown this flexibility to

be vital in achieving the goals listed above.

The goal of technical competence, the requirement for prior

implementation and testing, and the need to allow all interested

parties to comment all require significant time and effort. On the

other hand, today's rapid development of networking technology

demands timely development of standards. The Internet Standards

Process is intended to balance these conflicting goals. The process

is believed to be as short and simple as possible without sacrificing

technical excellence, thorough testing before adoption of a standard,

or openness and fairness.

From its inception, the Internet has been, and is expected to remain,

an evolving system whose participants regularly factor new

requirements and technology into its design and implementation. Users

of the Internet and providers of the equipment, software, and

services that support it should anticipate and embrace this evolution

as a major tenet of Internet philosophy.

The procedures described in this document are the result of a number

of years of evolution, driven both by the needs of the growing and

increasingly diverse Internet community, and by experience.

2. INTERNET STANDARDS-RELATED PUBLICATIONS

2.1 Requests for Comments (RFCs)

Each distinct version of an Internet standards-related specification

is published as part of the "Request for Comments" (RFC) document

series. This archival series is the official publication channel for

Internet standards documents and other publications of the IESG, IAB,

and Internet community. RFCs can be oBTained from a number of

Internet hosts using anonymous FTP, gopher, World Wide Web, and other

Internet document-retrieval systems.

The RFCseries of documents on networking began in 1969 as part of

the original ARPA wide-area networking (ARPANET) project (see

Appendix A for glossary of acronyms). RFCs cover a wide range of

topics in addition to Internet Standards, from early discussion of

new research concepts to status memos about the Internet. RFC

publication is the direct responsibility of the RFCEditor, under the

general direction of the IAB.

The rules for formatting and submitting an RFCare defined in [5].

Every RFCis available in ASCII text. Some RFCs are also available

in other formats. The other versions of an RFCmay contain material

(such as diagrams and figures) that is not present in the ASCII

version, and it may be formatted differently.

*********************************************************

* *

* A stricter requirement applies to standards-track *

* specifications: the ASCII text version is the *

* definitive reference, and therefore it must be a *

* complete and accurate specification of the standard, *

* including all necessary diagrams and illustrations. *

* *

*********************************************************

The status of Internet protocol and service specifications is

summarized periodically in an RFCentitled "Internet Official

Protocol Standards" [1]. This RFCshows the level of maturity and

other helpful information for each Internet protocol or service

specification (see section 3).

Some RFCs document Internet Standards. These RFCs form the 'STD'

subseries of the RFCseries [4]. When a specification has been

adopted as an Internet Standard, it is given the additional label

"STDxxx", but it keeps its RFCnumber and its place in the RFC

series. (see section 4.1.3)

Some RFCs standardize the results of community deliberations about

statements of principle or conclusions about what is the best way to

perform some operations or IETF process function. These RFCs form

the specification has been adopted as a BCP, it is given the

additional label "BCPxxx", but it keeps its RFCnumber and its place

in the RFCseries. (see section 5)

Not all specifications of protocols or services for the Internet

should or will become Internet Standards or BCPs. Such non-standards

track specifications are not subject to the rules for Internet

standardization. Non-standards track specifications may be published

directly as "Experimental" or "Informational" RFCs at the discretion

of the RFCEditor in consultation with the IESG (see section 4.2).

********************************************************

* *

* It is important to remember that not all RFCs *

* are standards track documents, and that not all *

* standards track documents reach the level of *

* Internet Standard. In the same way, not all RFCs *

* which describe current practices have been given *

* the review and approval to become BCPs. See *

* RFC-1796 [6] for further information. *

* *

********************************************************

2.2 Internet-Drafts

During the development of a specification, draft versions of the

document are made available for informal review and comment by

placing them in the IETF's "Internet-Drafts" directory, which is

replicated on a number of Internet hosts. This makes an evolving

working document readily available to a wide audience, facilitating

the process of review and revision.

An Internet-Draft that is published as an RFC, or that has remained

unchanged in the Internet-Drafts directory for more than six months

without being recommended by the IESG for publication as an RFC, is

simply removed from the Internet-Drafts directory. At any time, an

Internet-Draft may be replaced by a more recent version of the same

specification, restarting the six-month timeout period.

An Internet-Draft is NOT a means of "publishing" a specification;

specifications are published through the RFCmechanism described in

the previous section. Internet-Drafts have no formal status, and are

subject to change or removal at any time.

********************************************************

* *

* Under no circumstances should an Internet-Draft *

* be referenced by any paper, report, or Request- *

* for-Proposal, nor should a vendor claim compliance *

* with an Internet-Draft. *

* *

********************************************************

Note: It is acceptable to reference a standards-track specification

that may reasonably be expected to be published as an RFCusing the

phrase "Work in Progress" without referencing an Internet-Draft.

This may also be done in a standards track document itself as long

as the specification in which the reference is made would stand as a

complete and understandable document with or without the reference to

the "Work in Progress".

3. INTERNET STANDARD SPECIFICATIONS

Specifications subject to the Internet Standards Process fall into

one of two categories: Technical Specification (TS) and

Applicability Statement (AS).

3.1 Technical Specification (TS)

A Technical Specification is any description of a protocol, service,

procedure, convention, or format. It may completely describe all of

the relevant ASPects of its subject, or it may leave one or more

parameters or options unspecified. A TS may be completely self-

contained, or it may incorporate material from other specifications

by reference to other documents (which might or might not be Internet

Standards).

A TS shall include a statement of its scope and the general intent

for its use (domain of applicability). Thus, a TS that is inherently

specific to a particular context shall contain a statement to that

effect. However, a TS does not specify requirements for its use

within the Internet; these requirements, which depend on the

particular context in which the TS is incorporated by different

system configurations, are defined by an Applicability Statement.

3.2 Applicability Statement (AS)

An Applicability Statement specifies how, and under what

circumstances, one or more TSs may be applied to support a particular

Internet capability. An AS may specify uses for TSs that are not

Internet Standards, as discussed in Section 7.

An AS identifies the relevant TSs and the specific way in which they

are to be combined, and may also specify particular values or ranges

of TS parameters or subfunctions of a TS protocol that must be

implemented. An AS also specifies the circumstances in which the use

of a particular TS is required, recommended, or elective (see section

3.3).

An AS may describe particular methods of using a TS in a restricted

"domain of applicability", such as Internet routers, terminal

servers, Internet systems that interface to Ethernets, or datagram-

based database servers.

The broadest type of AS is a comprehensive conformance specification,

commonly called a "requirements document", for a particular class of

Internet systems, such as Internet routers or Internet hosts.

An AS may not have a higher maturity level in the standards track

than any standards-track TS on which the AS relies (see section 4.1).

For example, a TS at Draft Standard level may be referenced by an AS

at the Proposed Standard or Draft Standard level, but not by an AS at

the Standard level.

3.3 Requirement Levels

An AS shall apply one of the following "requirement levels" to each

of the TSs to which it refers:

(a) Required: Implementation of the referenced TS, as specified by

the AS, is required to achieve minimal conformance. For example,

IP and ICMP must be implemented by all Internet systems using the

TCP/IP Protocol Suite.

(b) Recommended: Implementation of the referenced TS is not

required for minimal conformance, but experience and/or generally

accepted technical wisdom suggest its desirability in the domain

of applicability of the AS. Vendors are strongly encouraged to

include the functions, features, and protocols of Recommended TSs

in their products, and should omit them only if the omission is

justified by some special circumstance. For example, the TELNET

protocol should be implemented by all systems that would benefit

from remote Access.

(c) Elective: Implementation of the referenced TS is optional

within the domain of applicability of the AS; that is, the AS

creates no explicit necessity to apply the TS. However, a

particular vendor may decide to implement it, or a particular user

may decide that it is a necessity in a specific environment. For

example, the DECNET MIB could be seen as valuable in an

environment where the DECNET protocol is used.

As noted in section 4.1, there are TSs that are not in the

standards track or that have been retired from the standards

track, and are therefore not required, recommended, or elective.

Two additional "requirement level" designations are available for

these TSs:

(d) Limited Use: The TS is considered to be appropriate for use

only in limited or unique circumstances. For example, the usage

of a protocol with the "Experimental" designation should generally

be limited to those actively involved with the experiment.

(e) Not Recommended: A TS that is considered to be inappropriate

for general use is labeled "Not Recommended". This may be because

of its limited functionality, specialized nature, or historic

status.

Although TSs and ASs are conceptually separate, in practice a

standards-track document may combine an AS and one or more related

TSs. For example, Technical Specifications that are developed

specifically and exclusively for some particular domain of

applicability, e.g., for mail server hosts, often contain within a

single specification all of the relevant AS and TS information. In

such cases, no useful purpose would be served by deliberately

distributing the information among several documents just to preserve

the formal AS/TS distinction. However, a TS that is likely to apply

to more than one domain of applicability should be developed in a

modular fashion, to facilitate its incorporation by multiple ASs.

The "Official Protocol Standards" RFC(STD1) lists a general

requirement level for each TS, using the nomenclature defined in this

section. This RFCis updated periodically. In many cases, more

detailed descriptions of the requirement levels of particular

protocols and of individual features of the protocols will be found

in appropriate ASs.

4. THE INTERNET STANDARDS TRACK

Specifications that are intended to become Internet Standards evolve

through a set of maturity levels known as the "standards track".

These maturity levels -- "Proposed Standard", "Draft Standard", and

"Standard" -- are defined and discussed in section 4.1. The way in

which specifications move along the standards track is described in

section 6.

Even after a specification has been adopted as an Internet Standard,

further evolution often occurs based on experience and the

recognition of new requirements. The nomenclature and procedures of

Internet standardization provide for the replacement of old Internet

Standards with new ones, and the assignment of descriptive labels to

indicate the status of "retired" Internet Standards. A set of

maturity levels is defined in section 4.2 to cover these and other

specifications that are not considered to be on the standards track.

4.1 Standards Track Maturity Levels

Internet specifications go through stages of development, testing,

and acceptance. Within the Internet Standards Process, these stages

are formally labeled "maturity levels".

This section describes the maturity levels and the expected

characteristics of specifications at each level.

4.1.1 Proposed Standard

The entry-level maturity for the standards track is "Proposed

Standard". A specific action by the IESG is required to move a

specification onto the standards track at the "Proposed Standard"

level.

A Proposed Standard specification is generally stable, has resolved

known design choices, is believed to be well-understood, has received

significant community review, and appears to enjoy enough community

interest to be considered valuable. However, further experience

might result in a change or even retraction of the specification

before it advances.

Usually, neither implementation nor operational experience is

required for the designation of a specification as a Proposed

Standard. However, such experience is highly desirable, and will

usually represent a strong argument in favor of a Proposed Standard

designation.

The IESG may require implementation and/or operational experience

prior to granting Proposed Standard status to a specification that

materially affects the core Internet protocols or that specifies

behavior that may have significant operational impact on the

Internet.

A Proposed Standard should have no known technical omissions with

respect to the requirements placed upon it. However, the IESG may

waive this requirement in order to allow a specification to advance

to the Proposed Standard state when it is considered to be useful and

necessary (and timely) even with known technical omissions.

Implementors should treat Proposed Standards as immature

specifications. It is desirable to implement them in order to gain

experience and to validate, test, and clarify the specification.

However, since the content of Proposed Standards may be changed if

problems are found or better solutions are identified, deploying

implementations of such standards into a disruption-sensitive

environment is not recommended.

4.1.2 Draft Standard

A specification from which at least two independent and interoperable

implementations from different code bases have been developed, and

for which sufficient successful operational experience has been

obtained, may be elevated to the "Draft Standard" level. For the

purposes of this section, "interoperable" means to be functionally

equivalent or interchangeable components of the system or process in

which they are used. If patented or otherwise controlled technology

is required for implementation, the separate implementations must

also have resulted from separate exercise of the licensing process.

Elevation to Draft Standard is a major advance in status, indicating

a strong belief that the specification is mature and will be useful.

The requirement for at least two independent and interoperable

implementations applies to all of the options and features of the

specification. In cases in which one or more options or features

have not been demonstrated in at least two interoperable

implementations, the specification may advance to the Draft Standard

level only if those options or features are removed.

The Working Group chair is responsible for documenting the specific

implementations which qualify the specification for Draft or Internet

Standard status along with documentation about testing of the

interoperation of these implementations. The documentation must

include information about the support of each of the individual

options and features. This documentation should be submitted to the

Area Director with the protocol action request. (see Section 6)

A Draft Standard must be well-understood and known to be quite

stable, both in its semantics and as a basis for developing an

implementation. A Draft Standard may still require additional or

more widespread field experience, since it is possible for

implementations based on Draft Standard specifications to demonstrate

unforeseen behavior when subjected to large-scale use in production

environments.

A Draft Standard is normally considered to be a final specification,

and changes are likely to be made only to solve specific problems

encountered. In most circumstances, it is reasonable for vendors to

deploy implementations of Draft Standards into a disruption sensitive

environment.

4.1.3 Internet Standard

A specification for which significant implementation and successful

operational experience has been obtained may be elevated to the

Internet Standard level. An Internet Standard (which may simply be

referred to as a Standard) is characterized by a high degree of

technical maturity and by a generally held belief that the specified

protocol or service provides significant benefit to the Internet

community.

A specification that reaches the status of Standard is assigned a

number in the STD series while retaining its RFCnumber.

4.2 Non-Standards Track Maturity Levels

Not every specification is on the standards track. A specification

may not be intended to be an Internet Standard, or it may be intended

for eventual standardization but not yet ready to enter the standards

track. A specification may have been superseded by a more recent

Internet Standard, or have otherwise fallen into disuse or disfavor.

Specifications that are not on the standards track are labeled with

one of three "off-track" maturity levels: "Experimental",

"Informational", or "Historic". The documents bearing these labels

are not Internet Standards in any sense.

4.2.1 Experimental

The "Experimental" designation typically denotes a specification that

is part of some research or development effort. Such a specification

is published for the general information of the Internet technical

community and as an archival record of the work, subject only to

editorial considerations and to verification that there has been

adequate coordination with the standards process (see below). An

Experimental specification may be the output of an organized Internet

research effort (e.g., a Research Group of the IRTF), an IETF Working

Group, or it may be an individual contribution.

4.2.2 Informational

An "Informational" specification is published for the general

information of the Internet community, and does not represent an

Internet community consensus or recommendation. The Informational

designation is intended to provide for the timely publication of a

very broad range of responsible informational documents from many

sources, subject only to editorial considerations and to verification

that there has been adequate coordination with the standards process

(see section 4.2.3).

Specifications that have been prepared outside of the Internet

community and are not incorporated into the Internet Standards

Process by any of the provisions of section 10 may be published as

Informational RFCs, with the permission of the owner and the

concurrence of the RFCEditor.

4.2.3 Procedures for Experimental and Informational RFCs

Unless they are the result of IETF Working Group action, documents

intended to be published with Experimental or Informational status

should be submitted directly to the RFCEditor. The RFCEditor will

publish any such documents as Internet-Drafts which have not already

been so published. In order to differentiate these Internet-Drafts

they will be labeled or grouped in the I-D directory so they are

easily recognizable. The RFCEditor will wait two weeks after this

publication for comments before proceeding further. The RFCEditor

is expected to exercise his or her judgment concerning the editorial

suitability of a document for publication with Experimental or

Informational status, and may refuse to publish a document which, in

the expert opinion of the RFCEditor, is unrelated to Internet

activity or falls below the technical and/or editorial standard for

RFCs.

To ensure that the non-standards track Experimental and Informational

designations are not misused to circumvent the Internet Standards

Process, the IESG and the RFCEditor have agreed that the RFCEditor

will refer to the IESG any document submitted for Experimental or

Informational publication which, in the opinion of the RFCEditor,

may be related to work being done, or expected to be done, within the

IETF community. The IESG shall review such a referred document

within a reasonable period of time, and recommend either that it be

published as originally submitted or referred to the IETF as a

contribution to the Internet Standards Process.

If (a) the IESG recommends that the document be brought within the

IETF and progressed within the IETF context, but the author declines

to do so, or (b) the IESG considers that the document proposes

something that conflicts with, or is actually inimical to, an

established IETF effort, the document may still be published as an

Experimental or Informational RFC. In these cases, however, the IESG

may insert appropriate "disclaimer" text into the RFCeither in or

immediately following the "Status of this Memo" section in order to

make the circumstances of its publication clear to readers.

Documents proposed for Experimental and Informational RFCs by IETF

Working Groups go through IESG review. The review is initiated using

the process described in section 6.1.1.

4.2.4 Historic

A specification that has been superseded by a more recent

specification or is for any other reason considered to be obsolete is

assigned to the "Historic" level. (Purists have suggested that the

Word should be "Historical"; however, at this point the use of

"Historic" is historical.)

Note: Standards track specifications normally must not depend on

other standards track specifications which are at a lower maturity

level or on non standards track specifications other than referenced

specifications from other standards bodies. (See Section 7.)

5. BEST CURRENT PRACTICE (BCP) RFCs

The BCP subseries of the RFCseries is designed to be a way to

standardize practices and the results of community deliberations. A

BCP document is subject to the same basic set of procedures as

standards track documents and thus is a vehicle by which the IETF

community can define and ratify the community's best current thinking

on a statement of principle or on what is believed to be the best way

to perform some operations or IETF process function.

Historically Internet standards have generally been concerned with

the technical specifications for hardware and software required for

computer communication across interconnected networks. However,

since the Internet itself is composed of networks operated by a great

variety of organizations, with diverse goals and rules, good user

service requires that the operators and administrators of the

Internet follow some common guidelines for policies and operations.

While these guidelines are generally different in scope and style

from protocol standards, their establishment needs a similar process

for consensus building.

While it is recognized that entities such as the IAB and IESG are

composed of individuals who may participate, as individuals, in the

technical work of the IETF, it is also recognized that the entities

themselves have an existence as leaders in the community. As leaders

in the Internet technical community, these entities should have an

outlet to propose ideas to stimulate work in a particular area, to

raise the community's sensitivity to a certain issue, to make a

statement of architectural principle, or to communicate their

thoughts on other matters. The BCP subseries creates a smoothly

structured way for these management entities to insert proposals into

the consensus-building machinery of the IETF while gauging the

community's view of that issue.

Finally, the BCP series may be used to document the operation of the

IETF itself. For example, this document defines the IETF Standards

Process and is published as a BCP.

5.1 BCP Review Process

Unlike standards-track documents, the mechanisms described in BCPs

are not well suited to the phased roll-in nature of the three stage

standards track and instead generally only make sense for full and

immediate instantiation.

The BCP process is similar to that for proposed standards. The BCP

is submitted to the IESG for review, (see section 6.1.1) and the

existing review process applies, including a Last-Call on the IETF

Announce mailing list. However, once the IESG has approved the

document, the process ends and the document is published. The

resulting document is viewed as having the technical approval of the

IETF.

Specifically, a document to be considered for the status of BCP must

undergo the procedures outlined in sections 6.1, and 6.4 of this

document. The BCP process may be appealed according to the procedures

in section 6.5.

Because BCPs are meant to express community consensus but are arrived

at more quickly than standards, BCPs require particular care.

Specifically, BCPs should not be viewed simply as stronger

Informational RFCs, but rather should be viewed as documents suitable

for a content different from Informational RFCs.

A specification, or group of specifications, that has, or have been

approved as a BCP is assigned a number in the BCP series while

retaining its RFCnumber(s).

6. THE INTERNET STANDARDS PROCESS

The mechanics of the Internet Standards Process involve decisions of

the IESG concerning the elevation of a specification onto the

standards track or the movement of a standards-track specification

from one maturity level to another. Although a number of reasonably

objective criteria (described below and in section 4) are available

to guide the IESG in making a decision to move a specification onto,

along, or off the standards track, there is no algorithmic guarantee

of elevation to or progression along the standards track for any

specification. The experienced collective judgment of the IESG

concerning the technical quality of a specification proposed for

elevation to or advancement in the standards track is an essential

component of the decision-making process.

6.1 Standards Actions

A "standards action" -- entering a particular specification into,

advancing it within, or removing it from, the standards track -- must

be approved by the IESG.

6.1.1 Initiation of Action

A specification that is intended to enter or advance in the Internet

standards track shall first be posted as an Internet-Draft (see

section 2.2) unless it has not changed since publication as an RFC.

It shall remain as an Internet-Draft for a period of time, not less

than two weeks, that permits useful community review, after which a

recommendation for action may be initiated.

A standards action is initiated by a recommendation by the IETF

Working group responsible for a specification to its Area Director,

copied to the IETF Secretariat or, in the case of a specification not

associated with a Working Group, a recommendation by an individual to

the IESG.

6.1.2 IESG Review and Approval

The IESG shall determine whether or not a specification submitted to

it according to section 6.1.1 satisfies the applicable criteria for

the recommended action (see sections 4.1 and 4.2), and shall in

addition determine whether or not the technical quality and clarity

of the specification is consistent with that expected for the

maturity level to which the specification is recommended.

In order to obtain all of the information necessary to make these

determinations, particularly when the specification is considered by

the IESG to be extremely important in terms of its potential impact

on the Internet or on the suite of Internet protocols, the IESG may,

at its discretion, commission an independent technical review of the

specification.

The IESG will send notice to the IETF of the pending IESG

consideration of the document(s) to permit a final review by the

general Internet community. This "Last-Call" notification shall be

via electronic mail to the IETF Announce mailing list. Comments on a

Last-Call shall be accepted from anyone, and should be sent as

directed in the Last-Call announcement.

The Last-Call period shall be no shorter than two weeks except in

those cases where the proposed standards action was not initiated by

an IETF Working Group, in which case the Last-Call period shall be no

shorter than four weeks. If the IESG believes that the community

interest would be served by allowing more time for comment, it may

decide on a longer Last-Call period or to explicitly lengthen a

current Last-Call period.

The IESG is not bound by the action recommended when the

specification was submitted. For example, the IESG may decide to

consider the specification for publication in a different category

than that requested. If the IESG determines this before the Last-

Call is issued then the Last-Call should reflect the IESG's view.

The IESG could also decide to change the publication category based

on the response to a Last-Call. If this decision would result in a

specification being published at a "higher" level than the original

Last-Call was for, a new Last-Call should be issued indicating the

IESG recommendation. In addition, the IESG may decide to recommend

the formation of a new Working Group in the case of significant

controversy in response to a Last-Call for specification not

originating from an IETF Working Group.

In a timely fashion after the expiration of the Last-Call period, the

IESG shall make its final determination of whether or not to approve

the standards action, and shall notify the IETF of its decision via

electronic mail to the IETF Announce mailing list.

6.1.3 Publication

If a standards action is approved, notification is sent to the RFC

Editor and copied to the IETF with instructions to publish the

specification as an RFC. The specification shall at that point be

removed from the Internet-Drafts directory.

An official summary of standards actions completed and pending shall

appear in each issue of the Internet Society's newsletter. This

shall constitute the "publication of record" for Internet standards

actions.

The RFCEditor shall publish periodically an "Internet Official

Protocol Standards" RFC[1], summarizing the status of all Internet

protocol and service specifications.

6.2 Advancing in the Standards Track

The procedure described in section 6.1 is followed for each action

that attends the advancement of a specification along the standards

track.

A specification shall remain at the Proposed Standard level for at

least six (6) months.

A specification shall remain at the Draft Standard level for at least

four (4) months, or until at least one IETF meeting has occurred,

whichever comes later.

These minimum periods are intended to ensure adequate opportunity for

community review without severely impacting timeliness. These

intervals shall be measured from the date of publication of the

corresponding RFC(s), or, if the action does not result in RFC

publication, the date of the announcement of the IESG approval of the

action.

A specification may be (indeed, is likely to be) revised as it

advances through the standards track. At each stage, the IESG shall

determine the scope and significance of the revision to the

specification, and, if necessary and appropriate, modify the

recommended action. Minor revisions are expected, but a significant

revision may require that the specification accumulate more

experience at its current maturity level before progressing. Finally,

if the specification has been changed very significantly, the IESG

may recommend that the revision be treated as a new document, re-

entering the standards track at the beginning.

Change of status shall result in republication of the specification

as an RFC, except in the rare case that there have been no changes at

all in the specification since the last publication. Generally,

desired changes will be "batched" for incorporation at the next level

in the standards track. However, deferral of changes to the next

standards action on the specification will not always be possible or

desirable; for example, an important typographical error, or a

technical error that does not represent a change in overall function

of the specification, may need to be corrected immediately. In such

cases, the IESG or RFCEditor may be asked to republish the RFC(with

a new number) with corrections, and this will not reset the minimum

time-at-level clock.

When a standards-track specification has not reached the Internet

Standard level but has remained at the same maturity level for

twenty-four (24) months, and every twelve (12) months thereafter

until the status is changed, the IESG shall review the viability of

the standardization effort responsible for that specification and the

usefulness of the technology. Following each such review, the IESG

shall approve termination or continuation of the development effort,

at the same time the IESG shall decide to maintain the specification

at the same maturity level or to move it to Historic status. This

decision shall be communicated to the IETF by electronic mail to the

IETF Announce mailing list to allow the Internet community an

opportunity to comment. This provision is not intended to threaten a

legitimate and active Working Group effort, but rather to provide an

administrative mechanism for terminating a moribund effort.

6.3 Revising a Standard

A new version of an established Internet Standard must progress

through the full Internet standardization process as if it were a

completely new specification. Once the new version has reached the

Standard level, it will usually replace the previous version, which

will be moved to Historic status. However, in some cases both

versions may remain as Internet Standards to honor the requirements

of an installed base. In this situation, the relationship between

the previous and the new versions must be explicitly stated in the

text of the new version or in another appropriate document (e.g., an

Applicability Statement; see section 3.2).

6.4 Retiring a Standard

As the technology changes and matures, it is possible for a new

Standard specification to be so clearly superior technically that one

or more existing standards track specifications for the same function

should be retired. In this case, or when it is felt for some other

reason that an existing standards track specification should be

retired, the IESG shall approve a change of status of the old

specification(s) to Historic. This recommendation shall be issued

with the same Last-Call and notification procedures used for any

other standards action. A request to retire an existing standard can

originate from a Working Group, an Area Director or some other

interested party.

6.5 Conflict Resolution and Appeals

Disputes are possible at various stages during the IETF process. As

much as possible the process is designed so that compromises can be

made, and genuine consensus achieved, however there are times when

even the most reasonable and knowledgeable people are unable to

agree. To achieve the goals of openness and fairness, such conflicts

must be resolved by a process of open review and discussion. This

section specifies the procedures that shall be followed to deal with

Internet standards issues that cannot be resolved through the normal

processes whereby IETF Working Groups and other Internet Standards

Process participants ordinarily reach consensus.

6.5.1 Working Group Disputes

An individual (whether a participant in the relevant Working Group or

not) may disagree with a Working Group recommendation based on his or

her belief that either (a) his or her own views have not been

adequately considered by the Working Group, or (b) the Working Group

has made an incorrect technical choice which places the quality

and/or integrity of the Working Group's product(s) in significant

jeopardy. The first issue is a difficulty with Working Group

process; the latter is an assertion of technical error. These two

types of disagreement are quite different, but both are handled by

the same process of review.

A person who disagrees with a Working Group recommendation shall

always first discuss the matter with the Working Group's chair(s),

who may involve other members of the Working Group (or the Working

Group as a whole) in the discussion.

If the disagreement cannot be resolved in this way, any of the

parties involved may bring it to the attention of the Area

Director(s) for the area in which the Working Group is chartered.

The Area Director(s) shall attempt to resolve the dispute.

If the disagreement cannot be resolved by the Area Director(s) any of

the parties involved may then appeal to the IESG as a whole. The

IESG shall then review the situation and attempt to resolve it in a

manner of its own choosing.

If the disagreement is not resolved to the satisfaction of the

parties at the IESG level, any of the parties involved may appeal the

decision to the IAB. The IAB shall then review the situation and

attempt to resolve it in a manner of its own choosing.

The IAB decision is final with respect to the question of whether or

not the Internet standards procedures have been followed and with

respect to all questions of technical merit.

6.5.2 Process Failures

This document sets forward procedures required to be followed to

ensure openness and fairness of the Internet Standards Process, and

the technical viability of the standards created. The IESG is the

principal agent of the IETF for this purpose, and it is the IESG that

is charged with ensuring that the required procedures have been

followed, and that any necessary prerequisites to a standards action

have been met.

If an individual should disagree with an action taken by the IESG in

this process, that person should first discuss the issue with the

ISEG Chair. If the IESG Chair is unable to satisfy the complainant

then the IESG as a whole should re-examine the action taken, along

with input from the complainant, and determine whether any further

action is needed. The IESG shall issue a report on its review of the

complaint to the IETF.

Should the complainant not be satisfied with the outcome of the IESG

review, an appeal may be lodged to the IAB. The IAB shall then review

the situation and attempt to resolve it in a manner of its own

choosing and report to the IETF on the outcome of its review.

If circumstances warrant, the IAB may direct that an IESG decision be

annulled, and the situation shall then be as it was before the IESG

decision was taken. The IAB may also recommend an action to the IESG,

or make such other recommendations as it deems fit. The IAB may not,

however, pre-empt the role of the IESG by issuing a decision which

only the IESG is empowered to make.

The IAB decision is final with respect to the question of whether or

not the Internet standards procedures have been followed.

6.5.3 Questions of Applicable Procedure

Further recourse is available only in cases in which the procedures

themselves (i.e., the procedures described in this document) are

claimed to be inadequate or insufficient to the protection of the

rights of all parties in a fair and open Internet Standards Process.

Claims on this basis may be made to the Internet Society Board of

Trustees. The President of the Internet Society shall acknowledge

such an appeal within two weeks, and shall at the time of

acknowledgment advise the petitioner of the expected duration of the

Trustees' review of the appeal. The Trustees shall review the

situation in a manner of its own choosing and report to the IETF on

the outcome of its review.

The Trustees' decision upon completion of their review shall be final

with respect to all aspects of the dispute.

6.5.4 Appeals Procedure

All appeals must include a detailed and specific description of the

facts of the dispute.

All appeals must be initiated within two months of the public

knowledge of the action or decision to be challenged.

At all stages of the appeals process, the individuals or bodies

responsible for making the decisions have the discretion to define

the specific procedures they will follow in the process of making

their decision.

In all cases a decision concerning the disposition of the dispute,

and the communication of that decision to the parties involved, must

be accomplished within a reasonable period of time.

[NOTE: These procedures intentionally and explicitly do not

establish a fixed maximum time period that shall be considered

"reasonable" in all cases. The Internet Standards Process places a

premium on consensus and efforts to achieve it, and deliberately

foregoes deterministically swift execution of procedures in favor of

a latitude within which more genuine technical agreements may be

reached.]

7. EXTERNAL STANDARDS AND SPECIFICATIONS

Many standards groups other than the IETF create and publish

standards documents for network protocols and services. When these

external specifications play an important role in the Internet, it is

desirable to reach common agreements on their usage -- i.e., to

establish Internet Standards relating to these external

specifications.

There are two categories of external specifications:

(1) Open Standards

Various national and international standards bodies, such as ANSI,

ISO, IEEE, and ITU-T, develop a variety of protocol and service

specifications that are similar to Technical Specifications

defined here. National and international groups also publish

"implementors' agreements" that are analogous to Applicability

Statements, capturing a body of implementation-specific detail

concerned with the practical application of their standards. All

of these are considered to be "open external standards" for the

purposes of the Internet Standards Process.

(2) Other Specifications

Other proprietary specifications that have come to be widely used

in the Internet may be treated by the Internet community as if

they were a "standards". Such a specification is not generally

developed in an open fashion, is typically proprietary, and is

controlled by the vendor, vendors, or organization that produced

it.

7.1 Use of External Specifications

To avoid conflict between competing versions of a specification, the

Internet community will not standardize a specification that is

simply an "Internet version" of an existing external specification

unless an explicit cooperative arrangement to do so has been made.

However, there are several ways in which an external specification

that is important for the operation and/or evolution of the Internet

may be adopted for Internet use.

7.1.1 Incorporation of an Open Standard

An Internet Standard TS or AS may incorporate an open external

standard by reference. For example, many Internet Standards

incorporate by reference the ANSI standard character set "ASCII" [2].

Whenever possible, the referenced specification shall be available

online.

7.1.2 Incorporation of Other Specifications

Other proprietary specifications may be incorporated by reference to

a version of the specification as long as the proprietor meets the

requirements of section 10. If the other proprietary specification

is not widely and readily available, the IESG may request that it be

published as an Informational RFC.

The IESG generally should not favor a particular proprietary

specification over technically equivalent and competing

specification(s) by making any incorporated vendor specification

"required" or "recommended".

7.1.3 Assumption

An IETF Working Group may start from an external specification and

develop it into an Internet specification. This is acceptable if (1)

the specification is provided to the Working Group in compliance with

the requirements of section 10, and (2) change control has been

conveyed to IETF by the original developer of the specification for

the specification or for specifications derived from the original

specification.

8. NOTICES AND RECORD KEEPING

Each of the organizations involved in the development and approval of

Internet Standards shall publicly announce, and shall maintain a

publicly accessible record of, every activity in which it engages, to

the extent that the activity represents the prosecution of any part

of the Internet Standards Process. For purposes of this section, the

organizations involved in the development and approval of Internet

Standards includes the IETF, the IESG, the IAB, all IETF Working

Groups, and the Internet Society Board of Trustees.

For IETF and Working Group meetings announcements shall be made by

electronic mail to the IETF Announce mailing list and shall be made

sufficiently far in advance of the activity to permit all interested

parties to effectively participate. The announcement shall contain

(or provide pointers to) all of the information that is necessary to

support the participation of any interested individual. In the case

of a meeting, for example, the announcement shall include an agenda

that specifies the standards- related issues that will be discussed.

The formal record of an organization's standards-related activity

shall include at least the following:

o the charter of the organization (or a defining document equivalent

to a charter);

o complete and accurate minutes of meetings;

o the archives of Working Group electronic mail mailing lists; and

o all written contributions from participants that pertain to the

organization's standards-related activity.

As a practical matter, the formal record of all Internet Standards

Process activities is maintained by the IETF Secretariat, and is the

responsibility of the IETF Secretariat except that each IETF Working

Group is expected to maintain their own email list archive and must

make a best effort to ensure that all traffic is captured and

included in the archives. Also, the Working Group chair is

responsible for providing the IETF Secretariat with complete and

accurate minutes of all Working Group meetings. Internet-Drafts that

have been removed (for any reason) from the Internet-Drafts

directories shall be archived by the IETF Secretariat for the sole

purpose of preserving an historical record of Internet standards

activity and thus are not retrievable except in special

circumstances.

9. VARYING THE PROCESS

This document, which sets out the rules and procedures by which

Internet Standards and related documents are made is itself a product

of the Internet Standards Process (as a BCP, as described in section

5). It replaces a previous version, and in time, is likely itself to

be replaced.

While, when published, this document represents the community's view

of the proper and correct process to follow, and requirements to be

met, to allow for the best possible Internet Standards and BCPs, it

cannot be assumed that this will always remain the case. From time to

time there may be a desire to update it, by replacing it with a new

version. Updating this document uses the same open procedures as are

used for any other BCP.

In addition, there may be situations where following the procedures

leads to a deadlock about a specific specification, or there may be

situations where the procedures provide no guidance. In these cases

it may be appropriate to invoke the variance procedure described

below.

9.1 The Variance Procedure

Upon the recommendation of the responsible IETF Working Group (or, if

no Working Group is constituted, upon the recommendation of an ad hoc

committee), the IESG may enter a particular specification into, or

advance it within, the standards track even though some of the

requirements of this document have not or will not be met. The IESG

may approve such a variance, however, only if it first determines

that the likely benefits to the Internet community are likely to

outweigh any costs to the Internet community that result from

noncompliance with the requirements in this document. In exercising

this discretion, the IESG shall at least consider (a) the technical

merit of the specification, (b) the possibility of achieving the

goals of the Internet Standards Process without granting a variance,

(c) alternatives to the granting of a variance, (d) the collateral

and precedential effects of granting a variance, and (e) the IESG's

ability to craft a variance that is as narrow as possible. In

determining whether to approve a variance, the IESG has discretion to

limit the scope of the variance to particular parts of this document

and to impose such additional restrictions or limitations as it

determines appropriate to protect the interests of the Internet

community.

The proposed variance must detail the problem perceived, explain the

precise provision of this document which is causing the need for a

variance, and the results of the IESG's considerations including

consideration of points (a) through (d) in the previous paragraph.

The proposed variance shall be issued as an Internet Draft. The IESG

shall then issue an extended Last-Call, of no less than 4 weeks, to

allow for community comment upon the proposal.

In a timely fashion after the expiration of the Last-Call period, the

IESG shall make its final determination of whether or not to approve

the proposed variance, and shall notify the IETF of its decision via

electronic mail to the IETF Announce mailing list. If the variance

is approved it shall be forwarded to the RFCEditor with a request

that it be published as a BCP.

This variance procedure is for use when a one-time waving of some

provision of this document is felt to be required. Permanent changes

to this document shall be accomplished through the normal BCP

process.

The appeals process in section 6.5 applies to this process.

9.2 Exclusions

No use of this procedure may lower any specified delays, nor exempt

any proposal from the requirements of openness, fairness, or

consensus, nor from the need to keep proper records of the meetings

and mailing list discussions.

Specifically, the following sections of this document must not be

subject of a variance: 5.1, 6.1, 6.1.1 (first paragraph), 6.1.2, 6.3

(first sentence), 6.5 and 9.

10. INTELLECTUAL PROPERTY RIGHTS

10.1. General Policy

In all matters of intellectual property rights and procedures, the

intention is to benefit the Internet community and the public at

large, while respecting the legitimate rights of others.

10.2 Confidentiality Obligations

No contribution that is subject to any requirement of confidentiality

or any restriction on its dissemination may be considered in any part

of the Internet Standards Process, and there must be no assumption of

any confidentiality obligation with respect to any such contribution.

10.3. Rights and Permissions

In the course of standards work, the IETF receives contributions in

various forms and from many persons. To best facilitate the

dissemination of these contributions, it is necessary to understand

any intellectual property rights (IPR) relating to the contributions.

10.3.1. All Contributions

By submission of a contribution, each person actually submitting the

contribution is deemed to agree to the following terms and conditions

on his own behalf, on behalf of the organization (if any) he

represents and on behalf of the owners of any propriety rights in the

contribution.. Where a submission identifies contributors in

addition to the contributor(s) who provide the actual submission, the

actual submitter(s) represent that each other named contributor was

made aware of and agreed to accept the same terms and conditions on

his own behalf, on behalf of any organization he may represent and

any known owner of any proprietary rights in the contribution.

l. Some works (e.g. works of the U.S. Government) are not subject to

copyright. However, to the extent that the submission is or may

be subject to copyright, the contributor, the organization he

represents (if any) and the owners of any proprietary rights in

the contribution, grant an unlimited perpetual, non-exclusive,

royalty-free, world-wide right and license to the ISOC and the

IETF under any copyrights in the contribution. This license

includes the right to copy, publish and distribute the

contribution in any way, and to prepare derivative works that are

based on or incorporate all or part of the contribution, the

license to such derivative works to be of the same scope as the

license of the original contribution.

2. The contributor acknowledges that the ISOC and IETF have no duty

to publish or otherwise use or disseminate any contribution.

3. The contributor grants permission to reference the name(s) and

address(es) of the contributor(s) and of the organization(s) he

represents (if any).

4. The contributor represents that contribution properly acknowledge

major contributors.

5. The contribuitor, the organization (if any) he represents and the

owners of any proprietary rights in the contribution, agree that

no information in the contribution is confidential and that the

ISOC and its affiliated organizations may freely disclose any

information in the contribution.

6. The contributor represents that he has disclosed the existence of

any proprietary or intellectual property rights in the

contribution that are reasonably and personally known to the

contributor. The contributor does not represent that he

personally knows of all potentially pertinent proprietary and

intellectual property rights owned or claimed by the organization

he represents (if any) or third parties.

7. The contributor represents that there are no limits to the

contributor's ability to make the grants acknowledgments and

agreements above that are reasonably and personally known to the

contributor.

By ratifying this description of the IETF process the Internet

Society warrants that it will not inhibit the traditional open and

free access to IETF documents for which license and right have

been assigned according to the procedures set forth in this

section, including Internet-Drafts and RFCs. This warrant is

perpetual and will not be revoked by the Internet Society or its

successors or assigns.

10.3.2. Standards Track Documents

(A) Where any patents, patent applications, or other proprietary

rights are known, or claimed, with respect to any specification on

the standards track, and brought to the attention of the IESG, the

IESG shall not advance the specification without including in the

document a note indicating the existence of such rights, or

claimed rights. Where implementations are required before

advancement of a specification, only implementations that have, by

statement of the implementors, taken adequate steps to comply with

any such rights, or claimed rights, shall be considered for the

purpose of showing the adequacy of the specification.

(B) The IESG disclaims any responsibility for identifying the

existence of or for evaluating the applicability of any claimed

copyrights, patents, patent applications, or other rights in the

fulfilling of the its obligations under (A), and will take no

position on the validity or scope of any such rights.

(C) Where the IESG knows of rights, or claimed rights under (A), the

IETF Executive Director shall attempt to obtain from the claimant

of such rights, a written assurance that upon approval by the IESG

of the relevant Internet standards track specification(s), any

party will be able to obtain the right to implement, use and

distribute the technology or works when implementing, using or

distributing technology based upon the specific specification(s)

under openly specified, reasonable, non-discriminatory terms.

The Working Group proposing the use of the technology with respect

to which the proprietary rights are claimed may assist the IETF

Executive Director in this effort. The results of this procedure

shall not affect advancement of a specification along the

standards track, except that the IESG may defer approval where a

delay may facilitate the obtaining of such assurances. The

results will, however, be recorded by the IETF Executive Director,

and made available. The IESG may also direct that a summary of

the results be included in any RFCpublished containing the

specification.

10.3.3 Determination of Reasonable and Non-discriminatory Terms

The IESG will not make any explicit determination that the assurance

of reasonable and non-discriminatory terms for the use of a

technology has been fulfilled in practice. It will instead use the

normal requirements for the advancement of Internet Standards to

verify that the terms for use are reasonable. If the two unrelated

implementations of the specification that are required to advance

from Proposed Standard to Draft Standard have been produced by

different organizations or individuals or if the "significant

implementation and successful operational experience" required to

advance from Draft Standard to Standard has been achieved the

assumption is that the terms must be reasonable and to some degree,

non-discriminatory. This assumption may be challenged during the

Last-Call period.

10.4. Notices

(A) Standards track documents shall include the following notice:

"The IETF takes no position regarding the validity or scope of

any intellectual property or other rights that might be claimed

to pertain to the implementation or use of the technology

described in this document or the extent to which any license

under such rights might or might not be available; neither does

it represent that it has made any effort to identify any such

rights. Information on the IETF's procedures with respect to

rights in standards-track and standards-related documentation

can be found in BCP-11. Copies of claims of rights made

available for publication and any assurances of licenses to

be made available, or the result of an attempt made

to obtain a general license or permission for the use of such

proprietary rights by implementors or users of this

specification can be obtained from the IETF Secretariat."

(B) The IETF encourages all interested parties to bring to its

attention, at the earliest possible time, the existence of any

intellectual property rights pertaining to Internet Standards.

For this purpose, each standards document shall include the

following invitation:

"The IETF invites any interested party to bring to its

attention any copyrights, patents or patent applications, or

other proprietary rights which may cover technology that may be

required to practice this standard. Please address the

information to the IETF Executive Director."

(C) The following copyright notice and disclaimer shall be included

in all ISOC standards-related documentation:

"Copyright (C) The Internet Society (date). All Rights

Reserved.

This document and translations of it may be copied and

furnished to others, and derivative works that comment on or

otherwise explain it or assist in its implmentation may be

prepared, copied, published and distributed, in whole or in

part, without restriction of any kind, provided that the above

copyright notice and this paragraph are included on all such

copies and derivative works. However, this document itself may

not be modified in any way, such as by removing the copyright

notice or references to the Internet Society or other Internet

organizations, except as needed for the purpose of developing

Internet standards in which case the procedures for copyrights

defined in the Internet Standards process must be followed, or

as required to translate it into languages other than English.

The limited permissions granted above are perpetual and will

not be revoked by the Internet Society or its successors or

assigns.

This document and the information contained herein is provided

on an "AS IS" basis and THE INTERNET SOCIETY AND THE INTERNET

ENGINEERING TASK FORCE DISCLAIMS ALL WARRANTIES, EXPRESS OR

IMPLIED, INCLUDING BUT NOT LIMITED TO ANY WARRANTY THAT THE USE

OF THE INFORMATION HEREIN WILL NOT INFRINGE ANY RIGHTS OR ANY

IMPLIED WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A

PARTICULAR PURPOSE."

(D) Where the IESG is aware at the time of publication of

proprietary rights claimed with respect to a standards track

document, or the technology described or referenced therein, such

document shall contain the following notice:

"The IETF has been notified of intellectual property rights

claimed in regard to some or all of the specification contained

in this document. For more information consult the online list

of claimed rights."

11. ACKNOWLEDGMENTS

There have been a number of people involved with the development of

the documents defining the IETF Standards Process over the years.

The process was first described in RFC1310 then revised in RFC1602

before the current effort (which relies heavily on its predecessors).

Specific acknowledgments must be extended to Lyman Chapin, Phill

Gross and Christian Huitema as the editors of the previous versions,

to Jon Postel and Dave Crocker for their inputs to those versions, to

Andy Ireland, Geoff Stewart, Jim Lampert, and Dick Holleman for their

reviews of the legal aspects of the procedures described herein, and

to John Stewart, Robert Elz and Steve Coya for their extensive input

on the final version.

In addition much of the credit for the refinement of the details of

the IETF processes belongs to the many members of the various

incarnations of the POISED Working Group.
