Well, I don't know much about TMMBR, so no doubt you are right. The point I was making was that __per se__ TFRC came across as a good predictor of available bandwidth; we never compared it against any other equivalent mechanisms, so I can't say whether it is the best of its class or what its strengths and weaknesses are relative to others of its class. We have started looking at the recent algorithm published by Harald and may have an opportunity to compare it against that of TFRC in our setup -best wishes, Abheek On Tue, Apr 17, 2012 at 6:59 PM, Zaheduzzaman Sarker <zaheduzzaman.sarker@ericsson.com> wrote:
TMMBR is a mechanism to request a ceiling in the bit-rate from a given RTP sender. TFRC is an algorithm to determine a transmission rate, or actually when it is time to transmit the next packet. TMMBR is only setting the ceiling value and the sender is allowed to chose any under that ceiling. Moreover, the RTP receiver needs algorithm around TMMBR to make it work for rate control.
Could you clarify how it would be possible to compared them?
