Most P2P VoD schemes focused on service architectures and overlays optimization without considering segments rarity and the performance of prefetching strategies. As a result, they cannot better support VCR-oriented services. Despite the remarkable popularity in VoD systems, there exists no prior work that studies the performance gap between different prefetching strategies. In this paper we analyze and understand the performance of different prefetching strategies. Our analytical characterization brings us not only a better understanding of several fundamental tradeoffs in prefetching strategies, but also important insights on the design of P2P VoD system. On the basis of this analysis, we finally proposed a cooperative prefetching strategy namely "COOCHING".In this strategy, the segments requested in VCR interactivities are prefetched into session beforehand using the information collected through gossips.
