Re: I-D ACTION:draft-ietf-megaco-reqs-09.txt
by Tom-PT Taylor 10 Dec '99

10 Dec '99

I propose WG Last Call based on this document, with the expiry two weeks hence (24 December). Changes from the previous version are as follows: - removed reqt 5.6 c) Support general test capabilities, for example loopbacks through the MG to test DSP operation. It was agreed that inward loopbacks are outside the scope of the protocol - they are not part of call control, so would be handled by some other maintenance protocol. Thus the above requirement is deleted. - reqt 5.7 a) - changed word call to connection - table in section 11 - removed wiretap - reqt 11.1.3.1 a) rewording of 2nd bullet on addressing - didn't mean wildcarding, meant instead allowing the gateway to choose (part of) the identifier The references need to be completed still, and there may be an editor's note or two that should still come out. > -----Original Message----- > From: Internet-Drafts(a)IETF.ORG [SMTP:Internet-Drafts@IETF.ORG] > Sent: Friday, December 10, 1999 8:08 AM > To: MEGACO(a)STANDARDS.NORTELNETWORKS.COM > Subject: I-D ACTION:draft-ietf-megaco-reqs-09.txt > > A New Internet-Draft is available from the on-line Internet-Drafts > directories. > This draft is a work item of the Media Gateway Control Working Group of > the IETF. > > Title : Media Gateway control protocol architecture and > requirements > Author(s) : N.

Question! MCU cascading
by Jun-young Heo 10 Dec '99

10 Dec '99

Hi everyone! I have a question about MCU cascading. I know MC cascading from reading H.323v2 recommendation. But, i'm not sure how to control media distribution. I think MasterMC knows only capset of local terminals connected directly. so, MasterMC can't make a SCM(selected communication mode) about all terminals. How MasterMC knows it? Eventually, I want to know about MP cascading excatly. One more question. Is SessionID in message related to logical channel and CommunicationModeCommand, distributed by MC? H.245 recommendation says, "Only the master can create the session identification." at p.81. But, Netmeeting and ViewStation which I tested create session ID itselft by convention(Audio:1, Video:2). Is it right? I wish experts advise to me. thanks for reading. bye.
