Re: H.248.1 - Examples for the Usage of the Statistics Descriptor
by Christian Groves 15 Dec '05

15 Dec '05

Hello Albrecht, The contribution certainly covers most use cases. I'm a little concerned that a 20 page appendix is an overkill for the description of statistics. I don't think the setting / resetting / deactivation is sufficiently different from normal properties/parameters to justify this amount of specification. If we go down the approach of document every case for the setting of statistics, do we need another appendix to show everycase for the setting of properties? another one to show call flows for the setting of signals. I think it is better to concentrate of the source of confusion and fix this rather than try to respecify the whole functionality. Unfortunately I couldn't make it to the last meeting to see the depth of confusion.

H.248.1 - Examples for the Usage of the Statistics Descriptor
by Albrecht.Schwarz＠alcatel.de 15 Dec '05

15 Dec '05

Dear All! With regards to our discussions last WP2/16 meeting and: > This is why I believe contributions are needed to April's meeting. I'd like to inform you that we drafted a contribution with a first proposal: See in http://ftp3.itu.int/av-arch/avc-site/Incoming/ file: http://ftp3.itu.int/av-arch/avc-site/Incoming/Alcatelt1%20T05-SG16-060403-D… After intensive studies of § 7.1.15 we did finally come to the conclusion what a new Appendix for H.248.1 on"Practices on Statistics ? Exemplary Use Cases" could be one way forward. Comments? Albrecht PS Yangbo, the specific capability you are looking for is in IV.5.7 ----- Forwarded message from Kevin Boyle <kboyle(a)nortel.com> ----- Date: Fri, 2 Dec 2005 10:06:14 -0500 From: Kevin Boyle <kboyle(a)nortel.com> Reply-To: Kevin Boyle <kboyle(a)nortel.com> Subject: RE: 1 Comm. with 2 Descr.;RE: Attach; Re: TD-46-1 6.4 Clarification of statistic reset capability To: albrecht.schwarz(a)ties.itu.ch, Yangbo Lin <linyangbo(a)huawei.com> There is certainly no *documented* capability in H.248 to allow the MGC to assign a value to a statistic.
