- NIC # 11118 BBN
- RFC # 376 8 August 1972
- Categories: F, G.3
- Updates: RFC #370
- Obsoletes: None
-
- NETWORK HOST STATUS
-
- This RFC reports on the status of most Network Hosts from
- July 31 to August 4.
-
- 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.
-
- NOTE: Ellen Westheimer left BBN to return to school on August 4.
- We therefore will discontinue the publication of these summaries.
- It is my understanding that UCLA-NMC is considering the publica-
- tion of similar, although more detailed, survey data in the near
- future; I hope that data will serve in lieu of these reports. In
- addition, of course, MIT-DMCG has had survey information available
- on line for some time (see RFC #308, NIC 9259.)

- _______________
- *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.

- _______________
- *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.
