A Selection Technique for Replicated Multicast Video Servers

Abstract— In this paper, we propose a selection technique for replicated multicast video streams from different servers. We assume that there exist replicated video servers, each of which encodes the same video into the ones of different quality levels and continuously transmits them as different multicast streams. Using an IGMP facility like mtrace, each receiver monitors packet count information of those streams on routers and periodically selects the one which is expected to provide low loss rate and to be suitable for the current available bandwidth of the receiver. Our technique is receiver-oriented, i.e., the behavior of each receiver is fully independent of the others. Nevertheless, congestion states can be dissolved autonomously so that the total amount of achieved quality at all the receivers can be as high as possible. Moreover, collection of packet count information is done in a scalable manner by sharing the collected information across the receivers efficiently. Our exp...
