NETWORK HOST STATUS
This RFC reports on the status of most Network Hosts from July 3 to
July 14.
No testing was done on July 4 as BBN took a holiday to celebrate
Independence Day. No testing was done on July 11 and 12 as I was on
vacation.
Several Hosts are currently excluded from the daily testing as they
are presently intended to be users only. Included here are the
Terminal IMPs, which are presently in the Network (AMES, MITRE, RADC,
NBS, ETAC, USC, GWC, NOAA, SAAC, ARPA, 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
138 Lincoln TSP
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.

where
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 within 60 seconds.)
