NETWORK HOST STATUS

This RFC reports 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.

RFC 319                   Network Host Status                 March 1972
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.
