In a P2P video-on-demand (VoD) system, the asynchronous characteristic of users' random seeking makes data sharing among peers more challenging, and raises very high capability requirement of the source video server. In this paper, we propose adding one more server in a P2P VoD system to support the random seeking operations and investigate the capacity(More)
Active measurement on peer-to-peer system is the best way to provide the real data for the system simulation and optimization. Based on coupon collector's problem, an optimized tracing model was proposed to guide the active measurement on BitTorrent swarm. With the optimization of lowering expectations and requesting concurrently, the information repetition(More)
