                              NETWORK HOST STATUS

       This RFC reports on the status of most Network Hosts from July 3 to
       July 14.

       No testing was done on July 4 as BBN took a holiday to celebrate
       Independence Day.  No testing was done on July 11 and 12 as I was on
       vacation.

       Several Hosts are currently excluded from the daily testing as they
       are presently intended to be users only.  Included here are the
       Terminal IMPs, which are presently in the Network (AMES, MITRE, RADC,
       NBS, ETAC, USC, GWC, NOAA, SAAC, ARPA, 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
       138               Lincoln         TSP
       12                Illinois        PDP-11
       19                NBS             PDP-11
       23                USC             IBM-360/44

       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.

       where
     D = Dead (Destination Host either dead or inaccessible [due to network
         partitioning or local IMP failure] from the BBN Terminal IMP.)
     F = Full (Destination Host opened a connection, informed user that all
         Network ports were in use, and immediately closed the connection.)
     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.
