基于主机性能评价的视频会议系统优化方案

组播技术的出现为基于P2P的视频会议系统提供了负载更小的开发方案,但在传统的组播技术支持下,分配到每台主机上的负载量依然可观。为解决突发负载问题,文中提出了一种基于主机性能评价的应用层组播算法,利用拓扑信息减少冗余数据在网络上传输,根据主机性能平衡负载分配,减轻主机负担。之后,在此组播算法之上,阐述了一种传统视频会议系统的优化实现方案。

Optimization scheme of video conference system based on host performance evaluation

The emergence of multicast technology provides a less load development scheme for P2 P based video conference system,but with the support of traditional multicast technology,the load allocated to each host is still considerable.In order to solve the problem of burst load,an application layer multicast algorithm is proposed based on host performance evaluation,which uses topology information to reduce redundant data transmission on the network,balances load distribution according to host performance,and reduces host burden.After that,based on the multicast algorithm,an optimized implementation scheme of traditional video conference system is described.
