Classification of Receivers in Large Multicast Groups using Distributed Clustering
Résumé
In this pap er, we describ e and evaluate a mecha-
nism for ltering RTCP receiver rep orts sent from
receivers to the whole session. In large multi-
cast groups, such feedbacks could induce network
congestion, receivers overload and feedback delay.
The prop osed ltering mechanism provides a clas-
sication of receivers according to a predened
similarity measure (e.g. packet loss rate observed
or TCP-friend ly bandwidth share). This mecha-
nism could b e used for example by layered trans-
mission schemes in which co ders adapt dynami-
cally the numb er and the rate of layers according
to clusters of receivers.
