A Measurement Study of P2P VoD System

Recently, as the rapid growth in the number of VoD system user, people ask for more and more video resources, which cause overload on server. Therefore, how to use the capability of peers to alleviate the server loading and at the same time maintaining the streaming performance becomes a new challenge for P2P technology. In this paper, after analyzing a large amount of data, we present some valuable results on user behavior and the performance of system. Then we discuss the relationship between user behavior, server load and quality of video. Our paper provides valuable insights which can improve VoD system.
