Hi, one more comment regarding the charter. I was wondering if there is a difference between congestion avoidance and congestion control. I would say congestion avoidance is the more general term, while congestion control implies some kind of control loop. In case of real-time media traffic, as we have specific traffic characteristics, we might end up with something that e.g. only switches between certain pre-defined rate depending on feedback that we maybe get (only) once per RTT. This is quite different form current (TCP) congestion control where you calculate the sending rate based on continuous feedback (assuming you have more or less all the time data to send). Would we consider both as congestion control or only the latter case which is TCP-like congestion control? I would propose to only talk about congestion avoidance in the charter to make sure that we not only aim for TCP-like congestion control but also a solution as described above would be in the charter.

Hi all,
There were two minimal changes to the charter, which is at: https://sites.google.com/a/alvestrand.com/rtp-congestion/bof-planning-page/ wg-charter---input-to-vancouver
It now explicitly says that the following are out of scope: * Active queue management; modifications to TCP of any kind; and * Multicast congestion control (common control of multiple unicast flows is in scope).
Other than that, the charter hasn't changed since the last version that was sent around in May.
Cheers, Michael
