+
+
+ 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
+ ADDRESS
+
+ 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
+ ADDRESS
+
+ 7 Rand IBM-360/65
+ 73 Harvard PDP-1
+ 12 Illinois PDP-11
+ 19 NBS PDP-11

+
+
+ * 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.
+
+ The tables on the next two pages summarize the Host status for this
+ period.

+RFC 288 Network Host Status January 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 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.
