Even if you should have missed this registration deadline or submission deadline (May 4), please be not discouraged to submit your contributions to the meeting. We would still welcome your valuable inputs. However, for fairness of the discussion, your contributions are marked as "late registration/submission" and their considerations are up to the agreement of the meeting. Please do not misunderstand that I am loosening the deadline, I am trying to achieve the best outcome of the meeting.

Error in H.245v9
by Paul E. Jones 24 Apr '04

24 Apr '04

Folks, It has been a while since a "serious" error has been identified in an H.323-related spec, but one was just recently discovered in H.245v9. I want to poll the people on the H.323 Implementers List and the SG16 mailing list to see what kind of impact we might have if we change this definition. The problem relates to the "FECData" CHOICE: http://www.packetizer.com/iptel/h245/h245_asn.html#MULTIMEDIA-SYSTEM-CONTRO… It is roughly defined like this: FECData ::= CHOICE { rfc2733 { ... stuff ... } } The problem is that there is no extension marker at the end of the "rfc2793" SEQUENCE, though it was intended that one be inserted. If you look at every other related definition (FECCapability and FECMode), you will see that they do contain an extension marker. We essentially have these ways to resolve this issue: 1.. Change the FECData definition to contain an extension marker 2.. Rename the "FECData" structure and references to something like "FECDataDeprecated" and add a new field called "FECData" and a new structure to go with it. This would mean no other text would have to change in H.323 or H.245 and no implementations would be impacted significantly: applications would be binary compatible, though two system implementing FEC might not open FEC protected channels correctly (one side thinking FEC is used and the other side not, for example). 3.. Create all new data structures and deprecate all current FEC data structures related to the "FECData" CHOICE We've had these kinds of problems in the past and simply corrected them via the H.323-Series Implementers Guide. However, it is always good to understand who, if anybody, will be impacted by such changes. Can you please provide me with information so that we can make an informed decision? Thanks, Paul E. Jones Rapporteur, ITU-T Q2/16 // www.packetizer.com

Cancellation of Q.K /16 meeting
by Leo.Lehmann＠bakom.admin.ch 20 Apr '04

20 Apr '04

Dear experts, Last week on April 13 was the deadline which I set for the reception of contributions regarding Q.K (mobility) for the rapporteur meeting in Beijing. Even if I was waiting one week longer I have not received any contribution so far. To justify a meeting, we need according the ITU-T rules a significant number of contributions and member organizations which want to attend. Due to the lack of contributions I regretfully have to announce that there will be NO meeting of Q.K/16 in May in Beijing. We have a tentative plan to hold a meeting in September (co-located with Q.D,F,G,1-5) if there is enough interest and a sufficient number of contributions. In the interim, I encourage everyone to progress our work by e-mail correspondence. Best regards, Leo Lehmann Rapporteur for Q.K/16

Request for Contributions to Q5/16 meeting in Beijing
by Robert R. Gilman 05 Apr '04

05 Apr '04

All- This is the first real meeting of the new Q5 NAT/Firewall Traversal question, and I'd like to solicit contributions to get the work started (but see also D-408 from the Geneva meeting). It seems especially appropriate to begin with discussions of requirements and architectures, and some examination of the existing body of work. Requirements might cover: - authentication of sources and sinks of traffic - authorization of sources/destinations to send/receive traffic. - network/realm topologies to be supported. - architectural principles - trust models - application scenarios - how to insure end-to=end privacy and integrity of application data, while permitting firewalls to authenticate the flows. - what we can require/use from existing firewalls (especially from the ubiquitous home firewalls.) - how to extend existing telephony protocols to free the firewall from knowledge of extraneous details of the protocols. I'm sure there are areas I've left out (like requirements for of any firewall control/request protocols.) At this stage, the field is wide open, so we need not limit ourselves to the above list. Another aspect of this work, I believe, is the need to involve the builders of firewalls. I don't believe we can be successful unless we can create a win/win situation for both the server and endpoint vendors and the firewall vendors. If any of you have contacts in the firewall market, please extend a personal invitation for them to join us. I'm looking forward to seeing you in Beijing. Thanks. -Bob ---------------------------------------------------- Bob Gilman rrg(a)avaya.com +1 303 538 3868
