- RFC #362 28 June 1972
- Categories: F, G.3
- Updates: RFC #353
- Obsoletes: None
-
- NETWORK HOST STATUS
-
- This RFC reports on the status of most Network Hosts from June 5
- to June 16. During this period the MIT Math Lab PDP-10 (Network
- address 198) became a server.
-
- No testing was done on June 6 due to an attempt to install the
- new IMP system. No testing was done on June 9 as the prototype
- Terminal IMP was being used for software debugging.
-
- On June 16 the ARPA Terminal IMP (Network 156) was installed in
- Arlington, Virginia.
-
- 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, RADC, SAAC, BELVOIR, 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
- 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.)
- _______________
- *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.
