摘要: 现有用户生产内容(UGC)类视频系统通常采用C/S架构设计,导致了视频服务器极大的带宽压力。提出一种采用对等网(P2P)的在线短视频查找策略——FastSearch,其目的是利用视频资源之间的关联关系进行视频资源定位,以显著提高点播节点之间的视频分享效率并降低对视频服务器的带宽需求。实验表明FastSearch具备良好的视频数据源节点查找能力,集成了该查找策略的短视频系统能有效减少对视频服务器的带宽消耗。

Abstract: Present User Generated Content (UGC) video system mainly adopts the client/server architecture, which can result in huge bandwidth pressure on streaming server. This paper proposed a Peer-to-Peer (P2P) based online short video search policy—FastSearch. It aims to make use of the relevancy relationship between video resources to locate resource, which can improve the sharing efficiency between peers and decrease the consumption of streaming server. The simulation results show that FastSearch has an efficient streaming source peers searching ability and can greatly reduce the bandwidth consumption of streaming server.

Key words: User Generated Content (UGC), Peer-to-Peer (P2P), resource search, social network, overlay network
