Editor's Note: Minutes received 8/3 CURRENT_MEETING_REPORT_ Reported by Jack Drescher/MCNC and Ari Ollikainen/LLNL Minutes of the Remote Conferencing BOF (REMCONF) Two BOF sessions were held on Remote Conferencing as a follow-on to the Teleconferencing Architecture BOFs held at the San Diego IETF in March. A preparatory meeting was added to the schedule between the first and second full BOFs. Sixty one different people attended either one or both BOF sessions. The stated purpose of the BOF was to present/solicit feedback on the first draft of the Remote Conferencing Architecture Outline/Structure, which had been sent to list prior to the IETF. Copies were also handed out prior to the first session. Other purposes were to solicit other major research efforts which might be relevant to the Remote Conferencing Architecture and to develop ties with these efforts as appropriate. Full Session of July 13, 1992 A brief statement of continuity from previous BOF sessions was reviewed along with the proposed Working Group Milestones. It was noted that the Group had not yet been able to achieve IESG approval as a Working Group. The main issue is ``broadness of Charter''. Yee-Hsiang Chang of MCNC presented the highlights of the first draft of the Remote Conferencing Architecture Outline. This architecture has a strong dependence on, and proposes extensions to, the Connection Control Protocol work being done at ISI. Among the points made during the ensuing discussion were: o Detailed configuration definitions are a good subject for this Group to work on. o Conference Directory Services should be based on X.500. o We need to develop a working relationship with the Security Working Group. o Capability for the ``loosely controlled conference'' (similar to the IETF broadcasts done from Boston) needs to be added to today's CCP. o We need to define what conferencing function APIs will be needed. o A restatement that this architecture proposes distributed conference servers. 1 o There was a request to ``define the problem to be solved'' or ``what function is desired''? o There was a request to have a tutorial on CCP in the next session. o It was suggested that we investigate the SMPTE header being developed by video and motion picture engineers. There was additional discussion on the proposed Working Group Charter and the ``sharpening'' of the proposed Charter required to gain Working Group status. A a special ``prep for Wednesday'' session, involving a smaller group, was scheduled on Tuesday evening, July 14. Special Session of Tuesday, July 14 A group of twelve people came to agreement on a statement of desired function and an approach to rewording of the proposed Working Group objectives, both to be presented at the 7/15 full session. A heavy emphasis on connection management and interface detail as a deliverable were the main discussion points on the revised Working Group objectives. Eve Schooler of ISI agreed to produce charts and give the CCP tutorial on 7/15, a repeat from the San Diego BOF. There was also consensus that the Group should discuss the subject of Conference Session Dynamics as a high priority item. Full session of July 15, 1992 The statement of desired function was presented and seemed to be well accepted as a first pass. A marked up REMCONF Working Group Goals chart was shown, with the changed emphasis highlighted. A reminder point was made that the ``Focus on'' chart notation means ``detailed deliverable''. The Connection Control Point tutorial was given. A point was made that other approaches to connection management, if available, should be evaluated along with CCP. A very brief discussion of the Touring Machine project at Bellcore, (presented at the San Diego BOF) was held and a request was made to include the description and API(new charts) in the minutes of the BOF. Future of the Group The organizational niche for the Remote Conferencing BOF has not been decided. Independently, we intend, at this time, to continue the discussions on the additions to CCP and to come to the November IETF with the first draft of the overall proposed Remote Conferencing Architecture, as called for in the proposed Working Group milestones. We would appreciate input from the Internet community on the referenced outline that's available via FTP and future expansions to it that will 2 be made available via announcement to rem-conf@es.net.
