A measurement study on user behavior of p2p VoD system

Nowadays, as the fast growth in population of p2p VoD system, user behaviors are playing an increasingly crucial role for the performance of system. In this paper, the user watching and sharing behaviors of p2p VoD system were studied by analyzing a large amount of real data. Then, a comparison between user behavior in p2p VoD system and other main kinds VoD systems was made. After that, a mathematic model was constructed to describe the characters based on those analyses. Finally, the correctness of conclusions was verified by an experiment on real system and an improved method was provided. Those studies were believed can possess guiding significance for analyzing system performance, traffic loads and studies on user behavior of other online applications.
