A New Design for Improvement of Scalable-RTCP

Abstract

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 one’s pros and cons, in addition to proposing new features.
