在多协议标签交换组播中应用合并组播树

Study of using aggregated multicast tree in MPLS

引入一种新的MPLS(多协议标签交换)组播实现方案———MPLS合并组播树,讨论了采用MPLS合并组播树在减少组播控制费用、故障恢复延迟、标签数等方面给MPLS组播带来的高效性,量化分析表明,采用MPLS合并组播树可以有效解决MPLS组播存在的标签数不足问题。

A new scheme of MPLS multicast——MPLS Aggregated Multicast Tree was introduced. Then the efficiency of MPLS aggregated multicast tree in reducing multicast control message overhead,delay of failure recovery and the number of label was discussed. The bounds on label reduction of MPLS Aggregated Multicast Tree were analyzed. The conclusion was that this solution was significant in label reduction.
