Scalability Solutions for Multimedia Real-time Control Protocol

Recently, some problems related to using the Real-time Control Protocol (RTCP) in a very large dynamic group have arisen. Some of these problems are: feedback delay, increasing storage state at every member, and ineffective RTCP bandwidth usage, especially for the receivers that obtain incoming RTCP reports through low bandwidth links. More schemes are proposed to alleviate the RTCP problems. The famous and the recent one, which was introduced by EL-Marakby and was named Scalable RTCP (S-RTCP), still have some drawbacks. This paper demonstrates a brief discussion and evaluation of existing schemes and algorithms. Comments on the proposed scheme and algorithm are introduced. Consequently, we demonstrate the design of More Scalable RTCP (MS-RTCP) scheme based on hierarchical structure, distributed management, and EL-Marakby scheme. Also, we show how our scheme will alleviate all the drawbacks that found in the S-RTCP. Finally, we will highlight this scheme implementation, analysis, and its performance evaluation.
