Can SCTP traffic cause congestion? I think not as control traffic is erratic and the bandwidth is negligible, especially when it's sharing the bandwidth with video & audio streams. If there is congestion on the line, it's not the data channels that are causing it, but the video ones and it's up to SRTP to fix it (and if someone is using data channels to transfer files they should add rate control).

That's why when data is lost, I'd like SCTP to retransmit and be aggressive about it. With the current congestion control, that means setting RTOMax to one second. If I could, I would probably like to retransmit even more often when network conditions are really bad.
