ABSTRACT
In this paper we examine the performance of two types of Overlaynetworks i.e. Peer-to-Peer (P2P) & Content Delivery Network(CDN) media streaming using Multiple Description Coding(MDC). In both the approaches many servers simultaneouslyserve one requesting client with complementary descriptions. Thisapproach improves reliability and decreases the data rate a serverhas to provide. We have implemented both approaches in the ns-2network simulator. The experimental results indicate that theperformance of Multiple Description Coding-based mediastreaming in case of P2P network is better than CDN.
