| 摘 要： | 视频会议在政务网络中有着广泛的应用,它在要求网络支持流媒体传输的同时,还要求将传播对象分别局限于各个特定范围内.传统的网络会议控制系统采用多条点对点传输来实现这种多播要求,这容易导致相同路径上的数据流拥塞.本文探讨在政务网络中多播路由、组管理协议以及链路层环境下的多播协议的具体应用技术,旨在为实现广泛而流畅的视频会议提供一种可行的解决方案.

| Abstract: | Multicast A/V conference technology, widely used in the e-government network,not only requires the network can carry the stream-media,but also needs the transmitted objects are respectively located in their given range.Traditional A/V conference control system uses the multiple point-to-point transmission to realize it,but this easily brings the congestion.In this paper,the authors discuss the IP multicast routing,Internet Group Management Protocol (IGMP) and the application of the multicast protocol in link layer,to provide an available resolution for the comprehensive and fluent A/V conference. |
