RFC-348 is titled “Discard Process”. It's authored by Jon Postel of UCLA and dated May 30, 1972.
The technical content
This is another of Postel's batch of RFCs submitted on May 30. It proposes a discard process: unlike the echo process of RFC-347, this process will listen for requests from remote hosts, open the connection, and then immediately discard any data that is sent.
Postel says this is useful for debugging but doesn't specify further than that. I'm guessing that it would be good for debugging “what happens if I send data to a valid, open remote process but never get a reply”?
