Classiication of Receivers in Large Multicast Groups Using Distributed Clustering

In this paper, we describe and evaluate a mechanism for ltering RTCP receiver reports sent from receivers to the whole session. In large multi-cast groups, such feedbacks could induce network congestion, receivers overload and feedback delay. The proposed ltering mechanism provides a clas-siication of receivers according to a predeened similarity measure (e.g. packet loss rate observed or TCP-friendly bandwidth share). This mechanism could be used for example by layered transmission schemes in which coders adapt dynamically the number and the rate of layers according to clusters of receivers.
