Network Working Group E. Westheimer Request for Comments: 288 BBN NIC: 8274 January 6, 1972 Obsoletes: None Updates: 287

                        NETWORK HOST STATUS
 This RFC reports on the status of most Network Hosts from December 20
 to December 30.  (On December 24 and December 31 BBN celebrated
 Christmas and New Year's Day respectively.)
 During these two weeks the Lincoln Labs TX2 (Network Address 112)
 became a server.
 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            SITE            COMPUTER
    133                BBN             PDP-10 (B)
    15                 Case            PDP-10
    13                 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:
    NETWORK             SITE           COMPUTER
    7                   Rand           IBM-360/65
    73                  Harvard        PDP-1
    12                  Illinois       PDP-11
    19                  NBS            PDP-11

Westheimer [Page 1] RFC 288 Network Host Status January 1972

  • 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.

Westheimer [Page 3] RFC 288 Network Host Status January 1972

    D = Dead (Destination Host either dead or inaccessible [due to
    network partitioning or local IMP failure] from the BBN Terminal
    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 second)
  • 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 indicated the NETRJS is also functioning.
    # These sites advertise that they may not have their system
    available at these times.
