Thank u Gunnar To clarify. I am not looking for a solution only in this specific scenario - though it is relevant... Assume I want the remote side to perform some specific changes, so I want to send a command or request to the remote side requesting it what to do. Would it be better to use RTCP? Lets say RTCP FB (rfc4585) or some new RTCP pacet type. Or maybe use a new RTP profile? I know both are optional but how would it be done? Ilan Doron From: avt-bounces@ietf.org [mailto:avt-bounces@ietf.org] On Behalf Of Gunnar Hellstr?m Sent: Wednesday, August 10, 2011 19:06 To: avt@ietf.org Subject: Re: [AVTCORE] Requesting redundancy level modification during a call Ilan, The decisions on levels to use in RFC 2198 was discussed some years ago when RFC 4103 Real-time text was created. It was then considered that the SDP for RFC 2198 shall not be seen as a full negotiation, but rather a declaration of capability to receive handle RFC 2198 and a declaration of the intended initial level of redundancy to be used if the other party also supports RFC 2198. >From that initial level, RTCP RR could be observed and judged if there is a need to increase the levels. The discussion is available in the avt archive from 2004. Part of it is here: ftp://ftp.ietf.org/ietf-mail-archive/avt/2004-04.mail Regards Gunnar ----------------------------------- Ilan Doron skrev 2011-08-10 16:07: Hello AVT Group :) (1st post here...) Assume a RTP call where rfc2198 redundancy is being used. During the call I want to request the remote side to modify redundancy level being used. Lets say request working with redundancy 2 instead of 1. What is the preferred method for this? RTP? RTCP? Other? 10x in advance.
