CURRENT MEETING REPORT Minutes for Internet Stream Protocol V2 Working Group (st2) Reported by: Tim O'Malley, BBN Corporation and Lou Berger, BBN Corporation The Working Group met for one session in Dallas. Lou Berger chaired the session. Tim O'Malley acted as scribe. The main focus of the session was the State Machine Internet-Draft, draft-ietf-st2-state-00.ps. The agenda for the session was: o Status of group o Implementation status o State machines discussion o Open Issues o Wrap-up There was also an administrative announcement. The Working Group mail and FTP server is being shutdown. The new server is located at BBN. The new server information is: o Mail List: st@bbn.com o Request Address: st-request@bbn.com o FTP Server: ftp://ftp.bbn.com/pub/st The status of the group was reviewed. The Working Group has accomplished the main chartered objective of publishing a revised protocol specification. The specification, RFC 1819, was issued over the summer. The only remaining work is the completion of the State Machine document. The state machine document has taken much longer to prepare than anticipated, but good progress has been made. Since the Working Group has completed its main chartered objective, and the technical work on State Machines is mostly complete, it was announced that the Working Group will close before the next IETF in March. There were no objections from the Working Group. The status report was followed by implementation reports from GMU and NTT. Professor Mark Pullen reported on a ST2+ Prototype being worked on at George Mason University. This work is an unsponsored, independent study project being conducted by several Masters Students. The goals of the project were to verify and implement ST2+ SCMP, and to define and implement a service (not ST specific) API. The project did not implement neighbor failure detection (HELLO), and used IP encapsulation. The work is partially complete, and is expected to be fully functional by February 1996. Professor Pullen reported that the most surprising aspect of the implementation was the amount of code needed to implement the API and the protocol. (The breakdown between the two was not known, but can be obtained from GMU.) The code is written is user space, and runs with Solaris on a Sparc . Muneyoshi Suzuki from NTT Telecommunications Networks Labs reported on an effort to build an ST2+ over ATM system. The work is in a planning phase and protocol design phase. They plan to have a finished implementation in 2 years. The work is focused on running over VBR and CBR, and mapping SCMP into Q.2931. The biggest difficulty encountered has been mapping the ST2+ FlowSpec into ATM. Mark Pullen commented that he too has seen this problem, and will raise the issue in the INT-SERV Working Group when appropriate. Sharon Sergeant, one of the State Machine document authors, then reviewed the Internet Draft. She gave an overview of the document, its structure, how the agent functions s map into state machines. She also reviewed the Retry and Control FSMs in detail. She reported that the main work remaining one the document is: o Language clarification o Minor technical corrections o Reorganization of document for clarification o Removal of implementation specific discussions She also solicited help in completing the draft. Mark Pullen offered to look for a student to help. A few people offered to review the document. The Working Group closed with a review of the decision to close the group by the next IETF and a review of action items for the draft. The next version of the document will include a major reorganization and minor technical corrections. It will be issued in mid-January. Then, based on feedback, another draft will be issued in mid-February. The desire is for this draft to be the final draft, and for it to be published as an Informational RFC by mid-March.
