- NIC #8303 18 January 1972
- Categories: F, G.3
- Updates: RFC 288
- Obsoletes: None
-
- NETWORK HOST STATUS
-
- This RFC reports on the status of most Network Hosts from January
- 3 to January 15.
-
- 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. Included here are:
-
- Network
- Address Site Computer
- ------- ---- --------
- 133 BBN PDP-10 (B)
- 8* SDC IBM-370/155
- 13 Case PDP-10
- 15 Ames/(Paoli) ILLIAC-(B6500)
-
- 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 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 SDC site is currently replacing their IBM 360/67 by an IBM
- 370/155. This site therefore is temporarily without any permanent
- Host on the network, and for this reason was not included in the daily
- testing for the preceding two weeks.
- **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
