+RFC #330 13 April 1972
+Categories: F, G.3
+Updates: RFC #326
+Obsoletes: None
+
+ NETWORK HOST STATUS
+
+This RFC reports on the status of most Network Hosts from March 27 to
+April 7. During this interval the PDP-10 at Ames which acts as a
+front-end to the Illiac (Network address 15) became a server.
+However, this Host will not be available to general use for several
+months. Also a Terminal IMP was installed at the University of
+Southern California (Network Address 23) on March 29.
+
+Several Hosts are currently excluded from the daily testing. These
+Host 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
+ Address Site Computer
+ ------- ---- --------
+ 134 MIT-AI PDP-10
+ 13 Case PDP-10
+
+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, 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
+
+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.

+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 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.
