摘要
针对基于智能建筑局域网的网络监控系统等宽带多媒体应用中,需要在二层以太网交换机上实现组播的问题,研究了目前二层以太网交换机上的3种主要组播协议:IGMP Snooping协议、CGMP协议和GMRP协议。对这3种协议的优缺点及其适用的智能建筑局域网环境进行了探讨,希望能为从事智能建筑研究和设计的人员提供有价值的参考。
Aim at the problems that multicast on the two-layer Ethernet exchanger is required in broadband multi-media applications of network monitoring system based on local area network of intelligent building. Three main mulficast protocols(IGMP Snooping, CGMP, GMRP) were analyzed. The advantages and disadvantages of three protocols and their applicable local area network environment of intelligent building were discussed to provide helpful reference for researchers and designers of intelligent building.
