                          NETWORK HOST STATUS

This RFC reports on the status of most Network Hosts from January
3 to January 15.

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:

       Address                Site            Computer
       -------                ----            --------
         133                  BBN             PDP-10 (B)
8* SDC IBM-370/155
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 Computer (Network Address 5) which is used solely for gathering statistics from the Network. Finally, included among these Hosts are the following:

       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. ______________ 370/155. This site therefore is temporarily without any permanent Host on the network, and for this reason was not included in the daily testing for the preceding two weeks. **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.

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.

#These sites advertise that they may not have their system available at these times.
