P2P VOD系统中实时资源调度管理的实现

Realization of Real-time Resource Management over P2P VOD System

在P2P VOD系统中针对音视频等实时资源的调度管理进行研究,并对媒体资源的发布、查找功能进行实现。构建域内、域间二级架构,用于管理系统中所有客户端上的资源。对客户端发布的媒体资源按照点播的起始时间进行分类管理,以便对媒体资源进行准确快速定位。提出资源参考点的计算方法,增强域内和域间资源的搜索功能。实验平台基于普通局域网的原型系统,对资源调度的基本操作原语的延时进行测试,结果能够满足客户的基本需求。

In this work, the real-time resource management over P2P VOD is researched, and distribution and query of media resource are realized. Double-layer structure including inter-domain and intra-domain is build to manage the resource on all clients, such as audio and video. Media classification according to demand-starting time is also considered in order to fast and accurate positioning of media resource. The reference points are set to the resource for the purpose of improving searching function of the inter-domain and intra-domain resource. Experimental prototype system based on LAN is realized, and thus the delays of basic operation primitives for the resource scheduling are tested. The testing results can meet the basic needs of customers.
