+Network Working Group Ellen Westheimer
+Request for Comments: 353 BBN
+NIC #10595 12 June 1972
+Categories: F, G.3
+Updates: RFC #344
+Obsoletes: None
+
+
+ NETWORK HOST STATUS
+
+ This RFC reports on the status of most Network Hosts from May 22 to
+ June 2.
+
+ No testing was done on Memorial Day, which Massachusetts celebrated
+ on May 29. No testing was done on May 31 and June 1 due to an
+ attempt to install the new IMP system.
+
+ Three new terminal IMPs were installed during this interval. On June
+ 1, Terminal IMP #155 was installed at Fort Belvoir in Fairfax,
+ Virginia; on June 3, Terminal IMP #154 was installed at SAAC (Seismic
+ Array Analysis Center) in Alexandria, Virginia; and on June 5,
+ Terminal IMP #153 was installed at NOAA (National Oceanic Analysis
+ Agency) in Boulder, Colorado.
+
+ 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, NOAA, SAAC, BELVOIR, and
+ BBN*). This category also includes the Network Control Center
+
+
+
+
+
+ ___________
+ *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.

+ statistics from the Network. Finally, included among these Hosts are

+ 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 opened a connection and was accessible to us.
