IP网络中高可靠性视频监控的组播设计

视频监控做为安全防范的一个重要手段已应用于各行各业,随着对视频监控的需求不断增加,传统的模拟视频监控技术已不能满足于人们对于图像质量高清、部署灵活、传输占用带宽小等应用的需求,逐渐转向基于IP承载网络的数字监控技术。那么如何使视频监控在IP网络中传输更稳定、可靠?本文将着重阐述如何基于组播技术规划、设计IP网络以满足在大型网络中视频监控的需求。

IP Multicast Design For High Reliability In Network Video Monitoring

Video surveillance is one of the most important secudty system tools that have been used in a wide variety of industries. Because the demand for video surveillance is increasing, traditional analogue video surveillance technology has been unable to meet the user＇s need for viewing high-quality images, flexible deployment and low occupied transmission bandwidth; it is gradually shifting to the demand IP bearer network-based digital surveillance technology but how can video surveillance in IP transmission across a network be made more stable and reliable. This article will focus on how group-based broadcast technology in the planning and design of IP network will meet needs in large network video surveillance.
