| 摘 要： | 目前,桌面会议、电子白板和视频广播等多播服务大都运行在局域网环境中,而绝大多数局域网结构,如以太网,都采用广播方式处理多播数据,对多播的支持有限.采用IGMP Snooping的方法,在二层交换机中设计一个基于VLAN和IGMP的多播协议,用于控制交换以太网中不断增长的IP多播流.描述了该协议的基本思想、语法和语义以及一个该协议验证和测试的过程.

| Abstract: | Many services, including video conference, whiteboard and video broadcasting, have been running over LANs. However, most of LANs, such as Ethernet, treat multicast just as broadcast, and they all have few supports for multicast. In this paper, a multicast protocol in an LAN switch, named IGMP snooping, is implemented based on VLAN and IGMP. IGMP snooping will be applied to the IP multicast stream control on the switch Ethernet. The basic idea, syntax and semantics of this protocol are given in this paper, and the verification and test procedure is also provided. |
