Re: H.GCP Audio Call postponed
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.

Collegues,
Bryan Hill is out-of-the office this week. He would like to postpone the audio call that was tentatively scheduled for Thursday to a later date. Please stay tuned. Thank you.

Colleagues,
The H.GCP audio call was held Thursday March 4th , 18 ports called in including a group from the TIPHON meeting. Companies represented were ATT, Lucent, ACGS, RadVision, Cisco, Nortel, Delta Information Systems, NetSpeak, Bellcore and others. . . The meeting opened by reviewing a proposed working model and fleshing out the work items that need to be addressed. A number of individuals committed to fleshing some of the work items prior to the next call, I would like to thank these individuals in advance. There was some news from TIPHON regarding changes to the reference model and some adjustments to the requirements they have contributed to H.GCP. These changes will be reflected once TDs from the Philadelphia meeting are released. The last hour or so was focussed on reviewing the H.GCP requirements I sent around prior to the meeting. The next call is tentatively planned for Thursday March 18 at 10AM EST.
The working model Individuals will be working up submissions to be reviewed by the entire group at the next audio call. The objective is that the principals involved will collaborate off line initially, post the results to the SG16 reflector for comments and a final version will be posted for discussion in an audio call. The result of that final review will be added into the H.GCP by the editor. Every effort will be made to resolve issues in this forum but if issues remain they will be logged and discussed in Santiago

Colleagues,
I would like to invite you to participate in audio call on Thursday March 4th from 11AM until 1PM EST to discuss H.GCP. The call details are as follows:
Calls from outside the US: 312-470-7273 Calls from within the US: 888-847-7598 Passcode: BryanHill Confirmation number: 5193957
Please respond to me directly to reserve a port for this call (where ever possible please try to minimize port requirements by sharing a port with a colleague).
The main purpose of this initial call will be to review requirements and terminology for H.GCP which were discussed in Monterey. I have been editing these sections and will make them available on the ptel SG16 ftp site no later than tomorrow 3/2. The second purpose of the call is to identify other areas that need to be discussed in subsequent audio calls. An initial pass of topics is listed below. I would like to solicit volunteers to submit written contribution in each of the areas identified and use these submissions as a basis for discussing topics in future audio calls. In this manner I hope to scope our discussion to specific technical topics and combine the benefits from MDCP and MGCP approaches into H.GCP.
1) Control model a) Controller to gateway associations b) Controller to internal gateway entity associations c) Failover d) Security 2) Connection model a) Controllable entities b) Controllable entity properties 3) Commands a) Types b) Parameters c) Acknowledgement styles/sequencing 4) Messages (i.e.-command packaging) 5) Message Encoding 6) Resource management 7) Scripting/Packages 8) Interface C protocol (Q.931/Q.764) 9) Interface B protocol (Q.931 )

Nancy, I'm sorry I didn't talk to you more during my stay at the IETF. I was not feeling well and it was a struggle to convince myself to even go to the meetings you set up. I didn't attend much else. Also, I didn't get around to thanking you for the excellent work you have done on this. I am lobbying for SG16 support of this draft that is coming out of our work. I'm pretty sure this is achievable. If we continue to work cooperatively at the grassroots level, the upper level people in the IETF and ITU will have no choice but to support us. I believe they want one solution too. Thanks again, Rex Nancy-M Greene wrote:
