- Categories: F, G.3
- Updates: RFC #326
- Obsoletes: None
-
- NETWORK HOST STATUS
-
- This RFC reports on the status of most Network Hosts from March 27 to
- April 7. During this interval the PDP-10 at Ames which acts as a
- front-end to the Illiac (Network address 15) became a server.
- However, this Host will not be available to general use for several
- months. Also a Terminal IMP was installed at the University of
- Southern California (Network Address 23) on March 29.
-
- Several Hosts are currently excluded from the daily testing. These
- Host 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
- ------- ---- --------
- 134 MIT-AI PDP-10
- 13 Case PDP-10
-
- 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, 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 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 times.
