This is only a rough draft - Megan 04/16/92 23rd IETF, San Diego Minutes of the Teleconferencing Architecture BOFs(TELARCH) March 16 and 18, 1992 Reported by: Jack Drescher/ MCNC Ari Ollikainen/LLNL Two BOF sessions were held on Teleconferencing Architecture as a follow-on to the Santa Fe IETF BOF on Teleconferencing and the Packet Video Videoconferencing Workshop at MCNC, both held in late 1991. The general objective of the BOFs was to move the process of forming a new Teleconferencing Architecture Working Group forward as much as possible. A proposed Draft Charter and set of Milestones was reviewed, relevant current work efforts were presented and discussed and a number of recommended action items were presented from the floor. A request for input to the future architecture content was made. Thirty-eight people attended all or part of the sessions. The Monday session was introduced by showing consistency of transition from the Santa Fe BOF minutes and the MCNC workshop objectives. The proposed draft of the Teleconferencing Architecture Working Group was presented in outline form, along with an initial set of milestones. A brief review of the MCNC Packet Video Project, for timing perspective, was presented. Eve Schooler, ISI, presented the Connection Manager and Connection Control Protocol work being done at ISI as part of the Multimedia Conferencing Project. Abel Weinrib, Bellcore, presented an additional (to Santa Fe BOF) presentation on the Touring Machine project at Bellcore. Both presentations were in response to the request for input to the overall teleconferencing architecture process. The objectives for the Wednesday session were reviewed. The Wednesday session was begun with some observations and discussion about the Audio/Visual Transport WG session and the Intellectual Property Law plenary presentation of Tuesday, 3/17. MCNC stated that they would name someone to be an active member of the AVT WG. It was also concluded that we all need to pay attention to Intellectual Property Law, that there was nothing unique about IPL to this Working Group, and that any information submitted to this WG and architecture produced by it should not be proprietary. Paul Milazzo of BBN led a presentation/discussion of a number of questions, issues and definitions requiring answers and clarification to better define and bound the architecture and work group charter. A summary of key points, conclusions, decisions follows: 1) The completed architecture, targeted for 1st Quarter 1993, needs to include: Supporting Protocols Statement of Conferencing Applications Supported Network Resources Required 2) Applications need to be modular and scalable. Models are needed. 3) "Groupware" needs to be better defined and expanded(as used in the draft charter) 4) Set a new milestone, as near in as possible, for sharper definition of applications supported. 5) Identify separation of pieces that make up the total Teleconferencing Architecture as soon as possible. Note: MCNC will try to provide first pass structure proposal for list to review by 5/01/92. 6) Question from floor:" Should we separate Connection Management from proposed Teleconferencing Architecture WG now?" ANS: We don't know enough about all the pieces to do that at this time". " Connection Management work should continue on its current course." Note: Agreement on 5) above should make questions like this easier to answer correctly. 7) Charter update process: Update charter, Pass by list for review, Submit to Russ Hobby for input to WG formalization process. Proposals Made: 1) Work Group mailing list, along with that of AVT WG, should be rem-conf@es.net. 2) Consider renaming proposed Teleconferencing Architecture WG to "Remote Conferencing" WG =================================================== Attendees: TELARCH BOFs of 3/16 and 3/18/92 San Diego Joe Blackmon blackmon@ncsa.uiuc.edu John Burnett jlb@adaptive.com Stephen Casner casner@isi.edu Cyrus Chow cchow@ames.arc.nasa.gov Richard Cogger rhx@cornell.cit.bitnet David Crocker dcrocker@mordor.stanford.edu Jack Drescher drescher@concert.net Maria Gallagher maria@nsipo.nasa.gov Tony Hain hain@es.net Russ Hobby rdhobby@ucdavis.edu Alton Hoover hoover@nis.ans.net H.
