Network Working Group Ellen Westheimer Request for Comments: 344 BBN NIC #10423 22 May 1972 Categories: F, G.3 Updates: RFC #342 Obsoletes: None

                        NETWORK HOST STATUS
 This RFC reports on the status of most Network Hosts from
 May 8 to May 19.  No testing was done on May 15 due to the attempt
 to install the new IMP system on that day.
 During this interval the PDP-10 of the MIT Artificial
 Intelligence Group (Network address 134) and the PDP-10 at
 Stanford (Network address 11) each became Network Servers.
 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.  The only
          Host in this category is the PDP-10 at Case (Network
          address 13).
      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, ETAC, USC, GWC, 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
            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.

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 with 60 seconds.) [Page 3] _

  • 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.
