+
+ NETWORK HOST STATUS
+
+ This RFC reports on the status of most Network Hosts from January 31
+ to February 11.
+
+ 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)
+ 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:
+
+ NETWORK SITE COMPUTER
+ ADDRESS
+
+ 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.
+
+ ________
+ *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.

+ 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 = Time 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.
