Re: [avtext] I-D Action: draft-ietf-avtext-sdes-hdr-ext-01.txt

WG,

This update performs a number of changes to the document.

- Makes it clearer that SDES header extensions is not suitable for all 
type of header extensions.

- Removes references to SRCNAME and APPID as the future of these are 
uncertain, and this document is planned to be finished before the end of 
the year.

- Expanded transmission considerations and some tips on what RTCP 
information that can be used to determine successful or at least failure 
to deliver.

- Discussion of how to avoid update flaps, a issue when sending both in 
RTP and RTCP.

- Much clarified registration rules and actual registration

- Various editorial updates.

We authors would really appreciate a review of this.

The timeplan is basically one more update before Prague and then 
hopefully a WG last call. To be able to do that we need your feedback on 
the changes and if something is still missing.

Cheers

Magnus Westerlund
(For the authors)

> Abstract:
>     Source Description (SDES) items are normally transported in RTP
>     control protocol (RTCP).  In some cases it can be beneficial to speed
>     up the delivery of these items.  Mainly when a new source (SSRC)
>     joins an RTP session and the receivers needs this source's identity,
>     relation to other sources, or its synchronization context, all of
>     which may be fully or partially identified using SDES items.  To
>     enable this optimization, this document specifies a new RTP header
>     extension that can carry SDES items.
