摘要
在现代网络中,视频/音频业务占据了越来越多的份额.文中针对网络接入设备如何更好地提供视/音频服务,提出一套可控组播的管理方案.分析比较2种不同的组播协议:IGMP Proxy和IGMP snooping协议,指出2种协议的差别和不足,阐述了接入网中引入组播控制和管理的必要性,讨论了相关的可控组播参数,给出一套实际的可控组播的管理方案,并分别对如何实现组播以及对其控制做了说明和论述.
Video/audio service has attracted more and more interest in current network. The aim of the paper is studying how to supply video/audio services better in access network device. Firstly two multicast protocol ： IGMP Proxy ＆ IGMP Snooping protocol are analyzed and compared, then the difference and disadvantages of the protocols are described,the necessity of importing multicast control and administration to access network devices is presented, some controllable multicast parameters are discussed. Finally a multicast control and administration scheme is presented; some experimental results are brought out in the end.
