RFC 326

Network Host Status

πŸ“… published April 1972, from ietf

Network Host Status ✨

Ellen Westheimer wrote this one πŸ’– from BBN (NIC # 9633), dated 3 April 1972. It's RFC # 326, filed under Categories F and G.3. It updates RFC #319 and obsoletes None 🌸.

Okay bestie, so this RFC is a status report. It tracks which Network Hosts were actually working between March 13 and March 24, and it's a whole vibe πŸ¦‹. During that stretch the SRI-AI computer became a server πŸ‘‘.

Some Hosts are currently left out of the daily testing πŸ’…. They fall into two groups, and I'm obsessed with how clean the split is 🧚.

  1. Hosts that aren't expected to be working on the Network as servers (available for use from other sites) on a regular basis for at least two weeks. That includes:
  Network
  Address                Site            Computer
  -------                ----            --------
    134                  MIT-AI          PDP-10
     13                  Case            PDP-10
  1. Hosts that are currently meant to be users only πŸ“. This group includes the Terminal IMPs, which are presently on the Network (AMES, MITRE, NBS, ETAC, and BBN*). It also has the Network Control Center computer (Network Address 5), which is used solely for gathering statistics from the Network πŸ“Š. And finally, these Hosts are in here too:
  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 sum up 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.

The Status Table πŸŽ€

Here's the big status table, with the "STATUS OR PREDICTIONS" column and everything πŸ’œ. Read it, don't just vibe with it πŸ™ˆ.

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.
