在远程监控系统的应用中，将多个现场的监控数据方便、高效地通过计算机网络传送到多台监控主机上，是需要解决的一个主要问题。为了有效地节约网络带宽、降低网络负载，文中设计了基于IP多播技术的远程监控系统；简要介绍了IP多播技术的概念、原理及体系结构；讨论了Winsock上实现IP多播和网络设备运行多播路由协议的方法；阐述了使用IP多播技术在远程监控系统中视频远程传输的设计思想和实现方法。

英文摘要：

In the application of remote monitoring system, putting a plurality of the monitoring data transfer to the multiple monitor host conveniently and efficiently, is one of the main problems need to solve. In order to save network bandwidth and reduce the load of net- work effectively, design the remote monitodttg and control system based on the IP multicast technology. Introduce the concept, principle and structure of system of IP multicast technology briefly. Discuss the method of realizing IP multicast in Winsock and the method of op- erating multicast muting protocol in the network equipment. Describe the use of IP multicast video design thought and the realization method of remote transmission in remote monitoring system technology.
