In recent years, a number of research efforts have focused on effective and stable P2P architectures aiming at large scale and low bandwidth cost, real time video streaming systems. In our work, we consider a BitTorrent-like VoD system and try to answer the following questions: (1) how we can dynamically manage a P2P overlay using distributed-scalable(More)
