摘要： 现有在线短视频分享策略通常采用C/S架构，给视频服务器带来较大的带宽压力。为此，提出一种采用点对点方式的在线短视频分享系统IShare，该系统结合用户点播偏好和视频文件之间的社会网络特性实现视频分享。IShare主要包括基于点播兴趣的节点分簇和视频数据源节点的查找2个核心技术。实验结果表明，IShare具备较好的视频数据源节点查找能力，可降低视频服务器带宽资源消耗。

Abstract: Online short video sharing is reshaping the way people watching videos, so this paper presents sharing policies mainly adopts the Client/Server architecture, which can result huge bandwidth pressure at streaming server. A P2P based online short video sharing System IShare is proposed, which combines viewing interests of users and social network characteristic of short videos, which can share short videos between users. IShare mainly includes interest based peers clustering and streaming source peers searching. Experimental results show IShare has a high efficient streaming source peers searching ability and can greatly reduce the bandwith consumption of streaming server.

Key words: Peer-to-Peer(P2P), searching algorithm, social network, overlay network, Video-on-Demand(VoD), interest cluster
