A New Design for Improvement of Scalable-RTCP

Real-time transport control protocol (RTCP) is the control protocol of real-time transport protocol (RTP), with responsibilities such as quality of service (QoS) adaptation, implementation, and troubleshooting. Various problems with RTCP have led to alternative designs, one of which is a hierarchical design named scalable-RTCP (S-RTCP). In this article, we explain about the weaknesses associated with S-RTCP (most of which are stability issues), and propose different approaches to solve the weaknesses, exposing each onepsilas pros and cons, in addition to proposing new features.
