Thank you for doing this work. I have a small number of comments you might consider. In this text: Note: The above is chosen to match the TCP initial window of 4 packets, not the larger TCP initial windows for which there is an ongoing experiment. The reason for this is a desire to be conservative, since an RTP endpoint will also in many cases start sending RTP data packets at the same time as these initial RTCP packets are sent. Not to be pedantic, but it would be more correct to say "TCP maximum initial window of 4 packets". RFC 3390 describes this in TCP-speak as Equivalently, the upper bound for the initial window size is based on the MSS, as follows: If (MSS <= 1095 bytes) then win <= 4 * MSS; If (1095 bytes < MSS < 2190 bytes) then win <= 4380; If (2190 bytes <= MSS) then win <= 2 * MSS; If you end up making changes to this text, providing RFC 3390 as the reference for 4 and RFC 6928 for the experiment would make the reader's job easier. In this text: The above algorithm has been shown in simulations to maintain the inter-RTCP packet transmission time distribution for each SSRC, and to consume the same amount of bandwidth as non-aggregated RTCP packets. is there a reference you could provide for the simulations? In this text: The finality of sending RTCP BYE, means that endpoints needs to consider if the ceasing of transmission of an RTP stream is temporary or more permanent. I don't understand the subtlety of "more permanent" - is this "permanent"?
