Classification of Receivers in Large Multicast Groups using Distributed Clustering
Kavé Salamatian, Thierry Turletti · 2001
In this paper, we describe and evaluate a mechanism for filtering RTCP receiver reports sent from receivers to the whole session. In large multicast groups, such feedbacks could induce network congestion, receivers overload and feedback delay. The proposed filtering mechanism provides a classification of receivers according to a predened 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.
