在视频监控联网系统中，传统独立部署的媒体服务器存在因并发导致的I／O负载严重、网络带宽不足以及负载分配不均等诸多问题。云媒体服务器将整体的调度、统一的管理和性能的优化融为一体，可实现资源利用的最优化和性能提升的最大化。本文研究并设计云媒体服务器的整体架构，基于此架构对服务器集群中媒体服务器的负载评判方法进行了设计。实验结果表明，相对于传统媒体服务架构的视频监控系统，云媒体服务器可较好地实现对业务的负载均衡、容错切换等功能，可以应对媒体服务器中对视频源的突发高并发访问。

In Video Surveillance Networking System, the traditional independent deployed media servers have many problems caused by concurrency of access including serious I/O load, insufficient network bandwidth, uneven distribution of load and so on.By the combination of overall scheduling, unified management and performance optimization, the cloud based media server can maximize the performance and resource utilization.The overall architecture of cloud media server was designed and the load evaluation method of the media server in server cluster was also designed based on this architecture.The experimental results show that compared with the traditional media server architecture, the cloud media server can handle the load balancing and fault tolerance switching well.It can deal with the sudden high concurrent access to the video sources of media servers.
