On Fairness and Locality in P2P-TV through Large-Scale Measurement Experiment

International audienceIn this paper, we present our P2P-TV measurement experiment performed in France and in Japan. By using multiple measurement points in different locations of the world, we are able to get a global view of the measured P2P networks and we can infer their main properties. More precisely, we focus on the level of collaboration between peers, their location and the effect of the traffic on the networks. Our results show that there is no fairness between peers and it is an important issue for the scalability of P2P-TV systems. Moreover, hundreds of Autonomous Systems are involved in the P2P-TV traffic and it points out the lack of locality-aware mechanisms for these systems. The geographic location of peers testifies the wide spread of these applications in Asia and highlights their worldwide usage
