Abstract

RTCP is the accompanying protocol to the RTP, which is very important for the feedback on the control of multimedia streaming services. The bandwidth for RTCP is related to the bandwidth available to the whole session and is limited to 5 %. This fact is a limiting factor for large scale media streaming services based on SSM because of bandwidth sharing among a large number of receivers. The paper describes the hierarchical structure of clients with summarisation nodes in wired and a mobile environment to assure that reporting interval does not exceed the maximum allowed value. Calculations and simulations are presented. The tree structure establishment process is designed.
