Updates: RFC315

NETWORK HOST STATUS

This RFCreports on the status of most Network Hosts from February 28

to March 10. The ETAC Terminal IMP (Network address 148) was

installed during this period.

Several Hosts are currently excluded from the daily testing. These

Hosts fall into two categories:

1) Hosts which are not eXPected to be functioning on the Network

as servers (available for use from other sites) on a regular

basis for at least two weeks. Included here are:

Network

Address Site Computer

------- ---- --------

134 MIT-AI PDP-10

13 Case PDP-10

15 Ames/(Paoli) ILLIAC/(B6500)

2) Hosts which are currently intended to be users only. Included

here are the Terminal IMP's which are presently in the Network

(AMES, MITRE, NBS and BBN). [The BBN Terminal IMP (Network

Address 158) is a prototype and as sUCh is frequently not

connected to the Network, but being used to refine and debug

the Terminal IMP programs.] This category also includes the

Network Control Center computer (Network Address 5) which is

used solely for gathering statistics from the Network.

Finally, included among these Hosts are the following:

Network

Address Site Computer

------- ---- --------

7 Rand IBM-360/65

73 Harvard PDP-1

12 Illinois PDP-11

19 NBS PDP-11

The tables on the next two pages summarize the Host status for this

period.

where

D = Dead (Destination Host either dead or inAccessible [due to

network partitioning or local IMP failure] from the BBN Terminal

IMP.)

H = 1/2 Open (Destination Host opened a connection but then either

immediately closed it, or did not respond any further.)

O = Open (Destination Host opened a connection and was accessible

to users.)

R = Refused (Destination Host returned a CLS to the initial RFC.)

T = Timed out (Destination Host did not complete the ICP and open

a connection within 60 seconds.)

The only service currently offered by the UCLA IBM-360/91 is a

Network Job Service (NETRJS), however, the BBN Terminal IMP is not

equipped to test NETRJS. We are assuming that initial connection to

the NETRJS logger indicates that NETRJS is also functioning.
