NETWORK HOST STATUS
This RFC reports on the status of most Network Hosts from January 17
to January 28.
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 SITE COMPUTER
ADDRESS
133 BBN PDP-10(B)
13 Case PDP-10
15 Ames/(Paoli) ILLIAC/(B6500)
2) Hosts which are currently intended to be users only. Included
here are the Terminal IMPs, which are presently in the Network
(AMES, MITRE, NBS and BBN*). This category also includes the
Network Control Center (Network Address 5) which is used solely
for gathering statistics from the Network. Finally, included
among these Hosts are the following:
NETWORK SITE COMPUTER
ADDRESS
7 Rand IBM-360/65
73 Harvard PDP-1
12 Illinois PDP-11
19 NBS PDP-11
NOTE: During this interval both the UTAH PDP-10 and the RAND PDP-10
became Network servers.
The tables on the next two pages summarize the Host status for this
period.
* 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.
