It totally does. Thanks!! Cheers, Michael On Apr 18, 2012, at 9:21 PM, Matt Mathis wrote:
Let me second Harald's point by making an observation: Your (Michael's) solution has two subtasks: proper real time Congestion Control for a single flow and multiplexing multiple playload types onto a single flow.
The short term agenda here is the first problem: proper real time CC for a single flow.
There is (probably) 100% agreement that we need some solution to the 2nd problem (or at least some similar problem).
But most of us do not want to put solving the second problem in the critical path for the first problem, which is essentially orthogonal.
Note that the first problem might be concurrently solved and tested for both SRTP and RRTCC, since we all believe the algorithm might be implemented in either.
Does this make sense?

I'm not sure my concerns about what is now called RRTCC are answered, but I think that we pretty much agree design-wise anyway. I'm now just a bit confused by the mix of 1) arguments against my suggestion to use only one congestion control instance for everything (ideally by making all RTCweb flows streams of one SCTP association), 2) some statements saying "yeah, this was the plan anyway".
Maybe it's because I don't know RTCweb well enough yet, or don't understand who does what and who plans what... and maybe it's also because I proposed too many intertwined things in one go (all-over-SCTP *and* one congestion control instance for everything). Whatever. Anyway, I think it's an interesting discussion :-)
Very possible - my take from RTCWEB side is that media over anything but SRTP is just not going to happen this year (or perhaps any year), for reasons having to do with installed base of a lot of stuff, while having a bridge for congestion control information to flow between the "media side" and the "sctp side" can be implemented in each implementation, and is such a no-brainer than everyone agrees we should Just Do It.
So since your note was "all in one go", it's no surprise that people seem to be saying yes AND no....
