As some of you know, at the IETF meeting in Minneapolis this week, a group
of us have reached agreement on a proposal for new connection model for the
device control protocol. We have been fortunate to have had, here in
Minneapolis, almost all the authors of existing internet-draft and ITU
contributions that address device control between a media gateway controller
and a media gateway (draft-huitema-megaco-mgcp-v0r1-05.txt,
draft-sijben-megaco-mdcp-01.txt, and
draft-cuervo-megaco-mgcp-compromise-00.txt). Bryan Hill and Glen Freundlich
were also here for part of the time.
The slides attached will give you a flavour for the work we are currently
documenting in a new internet-draft. We have presented the new connection
model to the megaco WG, and will be sending out the new internet-draft to
the megaco WG by the end of next week for comments. I hope to be able to
present this work at the next H.gcp conference call.
I think we have made a huge step forward by coming to an agreement on the
connection model, and am looking forward to having input from other SG16
members on the work we have begun.
