摘要
随着宽带接入的迅速普及,组播业务逐步得到应用,网络电视(IPTV)业务也正在走向商业运营,但是IPTV需要一个可控的组播对其提供支持,而组播协议并不是一个能对自身进行管理的协议。文章在介绍二层接入设备IP数字用户线接入复用器(IP DSLAM)上的组播协议的基础上,提出了一种在二级的IP DSLAM上如何支持可控组播的解决方案,并提供了详细的流程。
With the prevalence of broadband access, the muhicast services have gradually come into use. IPTV is the most focused service, which needs support by a controlled muhicast protocol, but the IGMP （internet Group Management Protocol） is not a protocol that is capable of self- management. In this article, a solution for the support of IPTV service by the controlled IGMP on IP DSLAM is described and the detailed flow chart presented.
