+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.

+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 with 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.
