Network Working Group Ellen Westheimer RFC #267 BBN NIC #7815 22 November 1971 Categories: F, G.3 Updates: RFC #266 Obsoletes None

This RFC reports on the status of most Network Hosts from November 8 to November 19. On November 18, however, the BBN prototype Terminal IMP (Network Address 158) was inaccessible due to hardware debugging.

Several Hosts are currently excluded fron 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) for at least two weeks. Included here are:

Network Address Site Computer

71 Rand PDP-10 74 Lincoln TX2 13 Case PDP-10 14 Carnegie PDP-10 15 Ames B6500 16 Ames IBM-360/67

2) Hosts which are curently intended to be users only. Included here are the Terminal IMPs, which are presently in the Network (AMES, MITRE, and BBN*). 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

During these two weeks the Lincoln Labs TX2 Hosts became a Network User. The SDC IBM 360/67 is now a server.

The tables on the next two pages summarize the information on 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.
