[Robutness] teleconferce -- March 1, 2000 11AM EST USA
by Maureen Stillman 24 Feb '00

24 Feb '00

The next robustness teleconference will be held on March 1, 2000 at 11AM EST USA. Please send me e-mail at maureen.stillman(a)nokia.com if you plan to attend so I can reserve sufficent resources. The dial in number is: (613)688-2795 The passcode is: 1235# (you must put in the pound sign) Agenda: 1) Discussion of the Robutness Framework document outline (attached) and 2) Solicit volunteers to fill in text for the outlined sections SG-16 Geneva meeting summary on robustness: The robutness ad hoc working group met several times and covered the following topics: 1) revisions to the Radvision submission on Robustness Procedure document Delayed-460. The revised document is WG2/TD 87 http://ties.itu.int/u/tsg16/sg16/td/wp2/2-087.doc. TD 87 was presented at the meeting and conditionally accepted for inclusion in H.323v4 and H.225. We are required to supply SDL for the robustness procedure by the SG-16 May, 2000 Rapporteur's meeting to ensure the document's ultimate inclusion in the standard. The robustness submission presented a robustness procedure for: * Detection of a TCP based connection failure * Synchronization of the two sides of the connection concerning the call state * Definition of recommended behavior in order to renew the call signaling connection and proceed as normal with the call * In the case of GK failure, the procedure allows calls to proceed without any interruption. 2) we worked on a Robustness framework outline (attached). The goal is to complete the framework document in time to submit it to the SG 16 meeting May 15-19. Here is some text from the opening summary: The H.323 series of Recommendations provides some support for building robust systems recommendations (e.g. support for specification of alternate gatekeepers and alternate endpoints). However, by themselves, these are incomplete. There are a number of unspecified issues such as: How are alternate endpoints and alternate gatekeepers used to "reconnect" calls that were in progress when a failure occurred? What signaling procedures are used to reconnect such calls and which device initiates the procedures? It is assumed that a well-defined model and explicit signaling procedures are needed to allow development of complete and interoperable solutions. However, no detailed procedures are specified in H.323 for dealing with system failures and re-establishing communication links after such a failure. This document proposes a framework towards providing robustness mechanisms in H.323 followed by the definition of robustness procedures for handling scenarios that are consistent with the framework. <<Robustness Framework 01.ZIP>> -- maureen Maureen Stillman Member of Scientific Staff Voice: (607)273-0724 x62 Nokia IP Telephony Fax: (607)275-3610 127 W.

Hi, Paul and Jaakko: Thanks for the update. I would propose that let Paul Guram control the TD numbers because Paul G. would be the single point of coordination (leaving no room for confusions either for Annex H, E, or I). I have a question to Jaakko related to the meeting minutes of Ad Hoc Mobility group of the last SG16 meeting: Why no mention about AT&T contributions (D.353 & D.354)? Would you please re-distribute the meeting minute updating the document stating the status of the AT&T contributions what exactly happened in the meeting? if you need help in this regard, please let me know. Best regards, Radhika R. Roy AT&T PS: A suggestion to Jaakko: With respect to TMSI, etc., I did not see any reference to any contributions in you email reply. Any additions/changes to the ITU document are made based on contributions. Only editorial changes are made by editors. In fact, TMSI, etc. were added when contributions were made and these were accepted after discussion. If there are problems, we would like to see more contributions explaining how these create problems. > -----Original Message----- > From: Guram Paul-LPG019 [SMTP:lpg019@EMAIL.MOT.COM] > Sent: Wednesday, February 23, 2000 7:16 PM > To: ITU-SG16(a)MAILBAG.INTEL.COM > Subject: Re: [H.323Mobility:] > > Hi ad hoc Mob.

Re: H.323-SIP Discussion

Hello all! I enjoyed to see a positive discussion this morning. Therefore I would like to move the topic to the SG-16 mailing list and indicate it by [H.323-Internet] topic. François, any ideas for an alternative name? "SIP" is limiting, "IETF" is political... Joon, I think that a "scope" chapter is a good idea. I completely agree that before diving into details of our contributions, we have to formulate this part. On the other hand, I see it as an output of our initial discussion, rather then its starting point. If you already have in mind some specifics on the scope chapter, go ahead and put them on the (mailing) paper. In regards to starting a formal joined work with IETF and pushing for a working group. It is a sensitive issue (Are we in agreement on that?) Everybody (as a company and as an individual) is free to join, initiate or participate in various standards bodies and pursue their goals. These initiatives can be helpful for our work as well. I wouldn't start our ITU work from formal definition of relationships with other standards bodies. As we can see from Henning's mail, the good will from all of us is a great starting point! I am afraid that not all of us will go to Australia. My company (as many others) will have representatives in SIP, Megaco and other relevant working groups. Nevertheless lets start the official H.323-Internet work at ITU. I hope to see more specific topics of interest and "a will" to address them in contributions for Osaka meeting. I will incorporate François' additions. Stephen, could you list IETF latest topics, list of services and level of scenarios that you would like to consider as a part of this work. I wouldn't like to address the same things as TIPHON and IETF do. They are doing very well and we may help them if needed. All of us have different interests, but my personal opinion is that - providing end user with end-to-end basic++ connectivity - enhancing H.323 by using IETF technologies (which definitely helps the first one) - finding common areas of interest among the companies are the criteria for defining our work items. BTW: Conference call is good, but lets do some work at home and on the mailing list before we have an agenda to discuss.

Hi, Orit: You are just right on time. I appreciate this. Please provide me couple of days (may be 2 more days). I would also like to include Henning S., Bahman M, Stephen T. and others in this mail. My understanding is that you are willing to work as an editor of this work in the SG16. Henning, just to let you know that SG16 has taken this as a work item. Going forward, we would also like to take this issue to the IETF to open a work item there as well. Tom indicated that Scott B. likes to see that there is enough support for this work item in the IETF before he considers whether it is worthwhile to open a new WG or to be a part of another WG. Tom might elaborate on this. I plan to attend the next IETF meeting in March'00. If we all plan to go there, we may push for this work in the IETF as well. I would request that all of us provide comments on this. If needed, we all may be the co-author of this document to show that we have a wide support for this paper. By the way, the next Q.13-14/16 Rapporteur meeting to be held in OSAKA, Japan (May 15-19) and any company can be the co-author of this document irrespective of the country of origin. Even Henning can also join in this contribution although Columbia University is not a member of the ITU-T because a Rap. can allow anyone to participate in the meeting. Let us start this with a great cooperative mode. Best regards, Radhika R.

Re: [H.323Mobility:]

Hi ad hoc Mob. Group 1. We will continue, as previously, and use the URL (ftp://standard.pictel.com/avc-site/Mobility-adhoc/ ) which has been allocated for our group's use. New contributions to start as (Mobility document) MDs to distinguish from the old numerous numbering schemes (for MTD,e.g. mtd03, mtd 201, etc.). I suggest we start at md010 as the first contribution with md001 to md009 to be used for management activities (to be defined later). When contributing, look at the ftp site for the next number available, reserve it by announcing to group, then (if no conflict of numbers) load it onto the site. OR we could ask one of Paul (R or G), Roy, or for Jaakko to control the allocation of the numbers, if you think that would be a better way which avoids clash of same number being used. 2. Jaakko has sent us the zipped file with the TD129 from Geneva for Annex H. This is the document Jaakko will work on as the base-line document and Jaakko, could this be put onto the ftp site as Annex H version 03 (version 01 being Red Bank output, version 2 being ad hoc group input into Geneva, and version 3 being Geneva output). Following on from Nicolas Tran's comments, there are already (minor) changes to be made to version 3, and this will be done as part of regular editor update. Similarly for the ToR document. Is that acceptable ? 3. Apart from Radhika, I have not received availability information for our next conf. call from anyone else. Please let me know which dates are most suitable from 20-24 March to enable me to arrange for an appropriate date.

Paul Guram: Please provide a well thought convention for the document number. For example, MTD.xxx would be given to diiferentiate from the reqular TDs. One request to you: Once a numbering convention is used, please try to stick to that rule (if we change the rule in the middle, it creates confusions as it happened last time).
