RFC 344
Network Host Status
RFC 344: Network Host Status β¨
Okay bestie, this is RFC 344 π¦ and it's a status report. Here's the title block, the important stuff first:
- Series: Network Working Group π
- RFC number: 344 π
- Author: Ellen Westheimer, BBN π
- NIC number: #10423
- Date: 22 May 1972 π
- Categories: F, G.3
- Updates: RFC #342 π₯
- Obsoletes: None
What This RFC Covers
This RFC reports on the status of most Network Hosts from May 8 to May 19 πΈ. No testing happened on May 15 because they tried installing the new IMP system that day π.
During this stretch, the PDP-10 of the MIT Artificial Intelligence Group (Network address 134) and the PDP-10 at Stanford (Network address 11) both became Network Servers πβ¨.
Some Hosts are currently excluded from the daily testing π. They fall into two categories:
- Hosts that aren't expected to be functioning on the Network as servers (available for use from other sites) on a regular basis for at least two weeks π§. The only Host in this category is the PDP-10 at Case (Network address 13).
- Hosts that are currently intended to be users only π. This includes the Terminal IMPs currently on the Network (AMES, MITRE, NBS, ETAC, USC, GWC, and BBN*). It also includes the Network Control Center computer (Network address 5), which is used solely for gathering statistics from the Network π. And finally, these Hosts are in this group too:
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 π.
*The BBN Terminal IMP (Network Address 158) is a prototype, so it's frequently not connected to the Network. It's being used to refine and debug the Terminal IMP programs π οΈ.

Legend π
Here's what the codes mean, so you can read the tables like a pro π§ :
D= Dead. The Destination Host is either dead or inaccessible (due to network partitioning or local IMP failure) from the BBN Terminal IMP π.F= Full. The Destination Host opened a connection, told the user that all Network ports were in use, and immediately closed the connection π.H= 1/2 Open. The Destination Host opened a connection but then either immediately closed it, or didn't respond any further π.O= Open. The Destination Host opened a connection and was accessible to users β¨.R= Refused. The Destination Host returned a CLS to the initial RFC π«.T= Timed out. The Destination Host didn't complete the ICP and open a connection with 60 seconds β³.
Footnotes π
*The only service currently offered by the UCLA IBM-360/91 is a Network Job Service (NETRJS). However, the BBN Terminal IMP isn't equipped to test NETRJS, so we're assuming that an initial connection to the NETRJS logger means NETRJS is also functioning π§.#These sites advertise that they may not have their system available at these times π.
