Hi,

I read the document and have a question about the multiple streams case.  Figure 2 adds the shared states module.  The text say
“The Rate Controller divides up the aggregate estimated bandwidth (1) from the Network Congestion Controller amongst sub-streams based on their relative priority levels, Shared States, as well as current occupancy level of the Transmission Queue.”
I am not sure what the shared state is but definitely in order to divide the bandwidth there is a need to know the required bw for each of the video streams (as a number or information about the encoding parameters like codec, resolution,…) this is a resource management algorithm that is needed here.

Hi everyone,



This draft has just expired and Zahed and I do plan to revive it soon. Currently we have on our "edit-to-address" list only some questions raised by Varun from IETF-96 (Berlin) regarding RTP taxonomy.  Varun has graciously agreed to provide some specific comments as follow-up, so we are waiting for those (thanks ahead Varun).



In the meantime, I would like to poll the mailing list to collect further review comments on this draft.  Please let us know what other issues you'd like us to address.

Thanks,

Xiaoqing
