摘　　要：交互性支持对P2P视频点播系统具有重要的意义,视频点播服务的大规模普及离不开用户交互性的支持。讨论了如何有效利用对等节点的带宽和存储资源来主动复制数据块,提出了一种基于云存储的数据复制策略CSPR。仿真实验结果表明,相比于现有的数据复制策略,CSPR可以显著提高用户进行随机搜索操作时的响应速度,并降低网络复制开销。It is important for P2P VoD systems to support user interaction. And it is inseparable for VoD service mass popu- larity to support user interaction. This paper discusses how to effectively use the bandwidth and storage resources of peer nodes to actively replication blocks of data. And it proposes a strategy called CSPR which is based on the Cloud storage data replication. The simulation results show that, compared with the existing data replication strategy, CSPR can significantly enhance the response of user random search operations, and reduce the overhead of replications.
