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
