2. Introduction

This memo defines a portion of the Management Information Base (MIB)

for use with network management protocols in the Internet community.

In particular, it defines objects for monitoring and controlling

network devices with HPR (High Performance Routing) capabilities.

This memo identifies managed objects for the HPR protocol.

3. The SNMP Network Management Framework

The SNMP Network Management Framework consists of several components.

For the purpose of this specification, the applicable components of

the Framework are the SMI and related documents [1, 2, 3], which

define the mechanisms used for describing and naming objects for the

purpose of management.

The Framework permits new objects to be defined for the purpose of

eXPerimentation and evaluation.

4. Overview

This document identifies objects for monitoring the configuration and

active characteristics of devices with HPR capabilities. HPR is an

enhancement to the Advanced Peer-to-Peer Network (APPN) architecture

that provides fast data routing and improved session reliability.

APPN is one of the protocols that can use the HPR transport

mechanism. See the SNANAU APPN MIB [4] for management of APPN and

APPN use of the HPR transport.

The HPR terms and overall architecture [5] are available at

http://www.networking.ibm.com/app/aiwdoc/aiwsrc.htm.

Automatic Network Routing (ANR) is a fast low-level routing

technique. Each node assigns a unique (within that node) ANR label

for each out-bound link as it is activated. The label size is

defined by the ANR node, and nodes only need to know how to interpret

their own labels. The ANR string is a group of ANR labels encoded in

a header in front of the message being sent. At each hop the node

strips off its own ANR label and forwards the message onto the link

with that label. The last label in the string is the Network

Connection Endpoint (NCE), which identifies the component within the

destination node that is to receive the message.

Rapid Transport Protocol (RTP) is an end-to-end full duplex transport

connection (pipe). It provides for high-speed transport of data

using ANR. RTP is connection-oriented, and delivers data in correct

order reliably. Error recovery is done efficiently with selective

retransmission of data. An RTP path can be switched without

disrupting the sessions using it. An RTP path switch may be done

automatically if a link in the path fails and another RTP path is

available, or on demand to attempt to restore the optimal path.

RTP performs flow/congestion control with the Adaptive Rate-Based

(ARB) algorithm, described in [5]. ARB is done only at the endpoints

of the RTP pipe, so intermediate hops are not involved.

ARB regulates the flow of data over an RTP connection by adaptively

changing the sender's rate based on feedback on the receiver's rate.

It is designed to prevent congestion rather than react to it.

In this document, we describe HPR managed objects.

Highlights of the management functions supported by the HPR MIB

module include the following:

o Identifying network connection endpoints (NCEs).

o Identifying how incoming packets are routed based on ANR labels.

o Monitoring the RTP connections between nodes.

o Ability to trigger an RTP path switch. The MIB only supports a

path switch with no specified path. Some implementations may

have a product-specific option to specify a new path. The

hprOperatorPathSwitchSupport object identifies this support.

o Historical information about RTP path switch attempts.

This MIB module does not support:

o Configuration of HPR nodes.

o Protocol-specific uses of HPR (such as APPN).

o Traps. The APPN MIB contains a trap for Alert conditions that

may affect HPR resources. The value for the affectedObject

object contained in the alertTrap is determined by the

implementation. It may contain a VariablePointer from the HPR

MIB. The APPN/HPR Alerts are defined in [6].

4.1. HPR MIB Structure

Although HPR is an extension to APPN, the HPR MIB relies very little

upon the APPN MIB. The appnNodeCounterDisconTime object in the APPN

MIB is used to detect discontinuities in HPR MIB counters. The

hprNodeCpName object in this MIB has the same value as the

appnNodeCpName object in the APPN MIB.

The HPR MIB module contains the following collections of objects:

o hprGlobal - general HPR objects.

o hprAnrRouting - objects related to the ANR routing table.

o hprTransportUser - objects related to users of the HPR

transport.

o hprRtp - objects related to the HPR Transport Tower.

These are described below in more detail.

4.1.1. hprGlobal group

The hprGlobal group consists of general objects such as the APPN CP

(control point) name of the HPR node and the level of support for

operator-requested path switches.

4.1.2. hprAnrRouting group

The hprAnrRouting group consists objects to monitor and control the

counting of ANR packets received and the following table:

The hprAnrRoutingTable correlates incoming ANR labels to the outbound

transmission group (TG) or local NCE to which incoming packet will be

forwarded. An entry defines the label type as identifying a local

NCE or a TG, identifies the NCE or TG, and counts the number of

packets received with the entry's ANR label.

4.1.3. hprTransportUser group

The hprTransportUser group consists of the following table:

The hprNceTable identifies network connection endpoints and their

function types. The function type can be any combination of a CP,

logical unit (LU), boundary function, and route setup.

4.1.4. hprRtp group

The hprRtp group consists of the following objects and tables:

1) hprRtpGlobe

These objects contain information about the number of RTP connection

setups, and control of RTP counters.

2) hprRtpTable

This table contains one entry for each RTP connection. The

information includes local and remote NCE IDs and TCIDs (transport

connection identifiers), timers, send rates, and statistics. A path

switch can be triggered by the hprRptPathSwitchTrigger object if the

agent node supports it; however, a new path cannot be specified.

3) hprRtpStatusTable

This table contains statistics and historical information for RTP

path switches attempts, including old and new ANR strings and Route

Selection Control Vectors (RSCVs), why the path switch was initiated,

and the result (successful or reason for failure).

-- The RTP Connection Status Table

-- This table contains statistics and historical information related to

-- both successful and unsuccessful RTP path switches. This

-- information can be important for both trend analysis and problem

-- determination.

--

-- Note the terminology here: when RTP is triggered to find a new path

-- for a connection, this initiates a 'path switch,' which will end up

-- being either successful or unsuccessful. During this path switch,

-- RTP will make one or more 'path switch attempts,' which are attempts

-- to find a new path for the connection and switch the connection to

-- it. This 'new' path may be the same path that the connection was

-- using before the path switch.

--

-- It is an implementation option how many entries to keep in this

-- table, and how long to retain any individual entry.

attempt failed because the

initiator is mobile, and

there was no active link

out of this node.

failed.

8. Security Considerations

In most cases, MIBs are not themselves security risks; if SNMP

security is operating as intended, the use of a MIB to view

information about a system, or to change some parameter at the

system, is a tool, not a threat.

None of the read-only objects in the HPR MIB reports a passWord, user

data, or anything else that is particularly sensitive. Some

enterprises view their network configuration itself, as well as

information about network usage and performance, as corporate assets;

such enterprises may wish to restrict SNMP access to most of the

objects in the MIB.

One read-write object in the MIB can affect network operations:

o hprRtpPathSwitchTrigger: Setting this object to 'switchPathNow'

triggers an immediate path switch attempt. An HPR path switch

does not itself disrupt the SNA sessions using the RTP

connection undergoing the path switch. However, frequent path

switches for many RTP connections can have an adverse impact on

overall network performance.

It is recommended that SNMP access to this object be restricted.

Other read-write objects control the gathering of network

management data; controlling access to these objects is less

critical.
