Specification Changes for OLS, RJE/RJOR, and SMFS ✨

Okay bestie, this is RFC 217 🎀, dated 8 September 71 and written by James E. White from the Computer Research Lab. at Univ. of California, Santa Barbara 🌸. It's also NIC 7547 💅. It's filed in category G.3, it updates RFC 105 and RFC 122 🦋, and it obsoletes RFC 74 💀. Let's get into it 🫶

The following documents are hereby revised 💖:

  • (1) 'Specifications for Network Use of the UCSB On-Line System [16 October 70, RFC 74, NIC 5417],
  • (2) 'Network Specifications for Remote Job Entry and Remote Job Output Retrieval at UCSB' [22 March 71, RFC 105, NIC 5775], and
  • (3) 'Network Specifications for UCSB's Simple-Minded File System' [26 April 71, RFC 122, NIC 5834].

Revisions are as follows 🌈:

  1. As far as anyone can tell, no Network site has written code to interface with the UCSB software documented in RFC 74 last October 😭. So UCSB has stopped supporting that software, which means RFC 74 is obsolete. Bye bye 👋
  2. Following later Host-Host protocol changes, the notion of 'message type' got dropped from the RJE and RJOR specifications in RFC 105 ✨. RJE and RJOR don't send, and don't expect to receive, 8 bits of zeros as the first byte transmitted over a connection anymore 🙈.
  3. Following Document 2, RJE and RJOR now use a standard ICP to set up a full duplex connection to the user 🔥. That means RJE and RJOR listen on sockets x'201' and x'301' now, instead of x'200' and x'300' like before 🧚. RFC 105 said RJE only needed a simplex connection to the user. Now a full duplex connection is supported too, but no data gets sent to the user over the added simplex connection. RJOR also supports a full duplex connection now 💜. Still, if RJOR has to call the user back when a requested job's output is ready, it does that over a simplex connection to the user's receive socket 🍓.
  4. RJE, RJOR, and SMFS specify a byte size of eight for their connection to the user's receive socket 🌸. The user can choose the byte size for the other simplex connection however they like, and UCSB accepts any valid byte size 💅✨.
