- RFC #344 22 May 1972
- Categories: F, G.3
- Updates: RFC #342
- Obsoletes: None
-
- NETWORK HOST STATUS
-
- This RFC reports on the status of most Network Hosts from
- May 8 to May 19. No testing was done on May 15 due to the attempt
- to install the new IMP system on that day.
-
- During this interval the PDP-10 of the MIT Artificial
- Intelligence Group (Network address 134) and the PDP-10 at
- Stanford (Network address 11) each became Network Servers.
-
- 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, 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 with 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.
