Summary:
This document discusses the types of congestion control feedback using the RTP Control Protocol. The document analyzes the feedback packet sizes and content for point-to-point Voice Telephony and point-to-point Conference call. 

Major issues:
Since most of today's conference bridges are multi-points to multi-points or at least multi-points (users) to multi-servers, I think multi-points analysis would be more useful. Will the author consider adding them? 

As for the Consideration of the RTCP feedback (Section 2), should you also consider how far away the endpoints are?  Will network congestion and distances impact the RTCP feedback? 

Section 1 states, "It is also assumed that the congestion control feedback mechanism in RFC8888, .. are available." Question: Is the Congestion Control Feedback mechanism described in this document the same as in RRC 8888? What are the key differences? 

Minor issues:
