视频监控系统一般采用客户端/服务器(C/S)模式。视频监控系统规模的扩大、应用由最初的安全监控向业务管理渗透,当用户过多时,C/S模式由于服务器自身性能以及网络带宽的限制,成为视频监控的瓶颈。本文采用P2P(Peer-to-Peer)的网络模型以及P2P的传输技术,构造适合视频监控系统的应用层组播树结构,充分利用了原监控客户端主机资源,解决了服务器和带宽的瓶颈问题,并对视频监控资源搜索技术进行研究。
Video surveillance systems generally use the client / server (C / S) mode. As the scale of video surveillance system expands, the application is infiltrated into the business management from the initial security monitoring. When the number of users is too high, the C / S mode becomes the bottleneck of video surveillance due to the limitation of server performance and network bandwidth. This paper uses Peer-to-Peer (P2P) network model and P2P transmission technology to construct an application-layer multicast tree structure suitable for video surveillance system. It fully utilizes the original monitoring client host resources and solves the bottleneck of server and bandwidth , And video surveillance resource search technology research.
