Hi Gorry, You are right that this may mitigate the issue if you have CN traffic. But I don't think that will happen for an VoIP application if the RTT is 100 ms. That represents commonly 5 frames. At that rate the rate of change of the transmission rate may be to slow to easily maintain a

Although I agree that CN packets are a function of the media codec, they *COULD* offer a mitigation to the effects of longer delay paths. When the Path RTT is short (e.g. less than a tenth of a second), then the TFRC algorithm already grows a window in a short time (e.g. still much less
