Abstract: Peer-to-peer networks are strongly based on cooperation. The users, called peers, communicate basically in a three-level based policy. In the first one, peers discover others interested in the same content, and is called swarm selection strategy (or swarming). Then, peers must select the best ones to cooperate, what is called peer selection strategy. Finally, peers cooperate sending pieces to each other, and the planning must attend the piece selection strategy. In this paper we propose an extension of a simple model based on cooperation for peer-to-peer video streaming networks. We assume that the swarming classifies peers according to their bandwidth. In this model we meet both the peer and the piece selection strategies, for simplified scenarios. The aim is to design network policies in order to achieve the highest continuity of video reproduction when peers reach a stationary state. We show that under full knowledge, the network can scale even under free-riding effects. At the sam e time, we provide theoretical results that reveal Rarest First has a poor performance in comparison with other techniques. Finally, we analyze the scalability in a worst-case scenario when a variable amount of special peers are included in the network. (More)
