RFC 376
Network Host Status
RFC 376: NETWORK HOST STATUS π
Network Working Group π Author: Ellen Westheimer (BBN) β¨ NIC #: 11118 πΈ RFC #: 376 π¦ Date: 8 August 1972 π Categories: F, G.3 π Updates: RFC #370 π₯ Obsoletes: None π
NETWORK HOST STATUS π
okay so this RFC is the host status report for basically every Network Host from July 31 to August 4. it's giving real-time network gossip π§
Several Hosts are currently excluded from the daily testing π because they're meant to be users only, no testing needed. The Terminal IMPs are still in the Network though, and they're the main ones here: AMES, MITRE, RADC, NBS, ETAC, USC, GWC, NOAA, SAAC, ARPA, and BBN*. π The Network Control Center computer (Network address 5) is also in this group. It's used only for gathering statistics from the Network, so it's the stats queen π. And finally, these Hosts are included too:

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 π
NOTE π
ngl this part is kind of sad π Ellen Westheimer left BBN to go back to school on August 4, so the team is stopping these summaries π Alex says UCLA-NMC is thinking about publishing similar survey data, and it'll be more detailed too! He's hoping that data replaces these reports π«Ά MIT-DMCG has also had survey info online for a while already (see RFC #308, NIC 9259), so there are options πΈ

*The BBN Terminal IMP (Network Address 158) is a prototype π§ͺ and as such is frequently not connected to the Network, because it's being used to refine and debug the Terminal IMP programs.

THE CODES π
Here's the decoder ring for those letters π
- D = Dead π: the Destination Host is either dead or inaccessible from the BBN Terminal IMP, whether because of network partitioning or a local IMP failure.
- F = Full π ββοΈ: the Destination Host opened a connection, told the user that all Network ports were in use, and immediately closed the connection.
- H = 1/2 Open π: the Destination Host opened a connection but then either immediately closed it, or stopped responding.
- O = Open β¨: the Destination Host opened a connection and was accessible to users.
- R = Refused π«: the Destination Host returned a CLS to the initial RFC.
- T = Timed out β°: the Destination Host didn't finish 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). The BBN Terminal IMP isn't equipped to test NETRJS, though, so we're assuming that a successful initial connection to the NETRJS logger means NETRJS is also functioning.
#These sites advertise that they may not have their system available at these times. π
