I *very* much agree with Roni here. I would argue that CPCP should have small primitives that applications can build arbitrarily complex behaviors. Let us not try to put everything in CPCP. As Roni has said in a few messages, reservation processing is extremely complex. There is no reason to put all of this into CPCP. Just starting and ending a conference is enough. All of the complex behaviors that people have been discussing can be built on this. > -----Original Message----- > From: Even, Roni [mailto:roni.even@polycom.co.il] > Sent: Wednesday, January 14, 2004 10:14 AM > To: 'Michael Hammer'; Even, Roni > Cc: 'Drage, Keith (Keith)'; 'Rosen, Brian'; Even, Roni; > 'hisham.khartabil@nokia.com'; xcon@ietf.org > Subject: RE: [XCON] CPCP Requirement: de-activating a conference > > > Mike, > This is a service that is not available by all conference > bridges and will > need to be implemented by an application server that will use > CPCP to start > the breakout session and invite the participants to it. > What happens in the end of the breakout session, does the > conference bridge > bring all to the main conference, can the moderator extend > it,, all these > are applications and not part of the conference service in my view > Roni > > > > > -----Original Message----- > From: Michael Hammer [mailto:mhammer@cisco.com] > Sent: Wednesday, January 14, 2004 5:02 PM > To: Even, Roni > Cc: 'Drage, Keith (Keith)'; 'Rosen, Brian'; Even, Roni; > 'hisham.khartabil@nokia.com'; xcon@ietf.org > Subject: RE: [XCON] CPCP Requirement: de-activating a conference > > > Roni, > > I am still a little fuzzy on what is/is not being addressed. > > For example, if the conference moderator wanted to create > breakout sessions > with defined start and stop times with assigned participants, > could this be > setup with CPCP such that the breakouts are created in 10 > minutes, then > terminate after another 10 minutes?
