RFC 332
Network Host Status
Okay bestie, let's get into it 🎀
Before anything else, here's the vibe check on this doc 💅 It's RFC 332, titled NETWORK HOST STATUS, written by Ellen Westheimer at BBN (NIC #9925) and dated 25 April 1972. It's filed under Categories F and G.3, it Updates RFC #330, and it Obsoletes None 🦋 So it's building on RFC 330 without replacing anything.
NETWORK HOST STATUS 🌸
So this RFC is basically a status report on most of the Network Hosts from April 10 to April 21 🧚 During that stretch, the IBM 360/44 at the University of Southern California (Network Address 23) got connected to the Network ✨ Also, a Terminal IMP was installed in Omaha, Nebraska at Global Weather Central (Network Address 152) on April 18 🌈
Several Hosts are currently excluded from the daily testing 🙈 They fall into two categories, and honestly the way they're sorted is so organized it's giving 👑
- 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 💀 The ones in this group are:
Network
Address Site Computer
------- ---- --------
134 MIT-AI PDP-10
13 Case PDP-10- Hosts that are currently meant to be users only 💜 This group includes the Terminal IMPs, which are presently in the Network (AMES, MITRE, NBS, ETAC, USC, GWC, and BBN*). It also covers the Network Control Center computer (Network Address 5), which is used solely for gathering statistics from the Network 📊 And finally, the following 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
23 USC IBM-360/44The tables on the next two pages summarize the Host status for this period 🍓
*The BBN Terminal IMP (Network Address 158) is a prototype, so it's frequently not connected to the Network 🙈 It's mostly being used to refine and debug the Terminal IMP programs.
Here's the big status table, aka "STATUS OR PREDICTIONS" 💖 with a few of the sites' dads... I mean, the people who gave the info 🫶

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 within 60 seconds.)Last few footnotes, and then we're done 🧚
*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, so we are assuming that an initial connection to the NETRJS logger indicates that NETRJS is also functioning.
