摘　　要：该文首先介绍了基于VPN的实时视频监控系统的架构和原理,由于一些视频监控应用提出多点接收的需求,为解决这个问题该文将多播技术应用于视频监控网络,进行了系统实现,同时讨论了多播带来的安全性问题,在VPN网环境下测试表明,采用多播技术可以较好地解决实时视频监控系统中的多用户接收问题,同时安全性也得到了一定的保证。This paper introduces architecture and principle of video surveillance system based on VPN.Since some video surveillance application proposes multi-point receiving requirement,this paper uses multicast technology in video surveillance system in order to solve this problem.It realizes multicast communication and briefly discusses the multicast security problems.In a VPN environment tests show that,using multicast technology can effectively solve more user reception problems in the real-time video surveillance system,and meanwhile security has also been a certain guarantee.
