-
- NETWORK HOST STATUS
-
- This RFC reports on the status of most Network Hosts from July 17
- to July 28.
-
- On Tuesday, July 18, the new IMP software was released.
-
- 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.

-
- 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.)
