摘　　要：提出一种基于兄弟节点备份的MPLS聚合多播故障恢复方案SBAMM,一方面,能够以快而准的方式绕过单链路和单节点故障,另一方面扩大了保护范围;最后优化了保护树的开销。另外,由于该方案是基于MPLS网络提出的,此方案也具有MPLS所具有的优点。结果分析表明,此方案具有更好的保护率、减低多播分发树的开销等优势。This paper proposed SBAMM(sibling-based backup aggregated multicast in MPLS) fault-tolerant approach,on the one hand,it could deal with single link and node failure in a quick and nice way,and on the other hand,it would enlarge the protecting area.Finally,it could optimize the cost of maintaining backup tree.In addition,the SBAMM scheme was more excellenf than MPLS.By analysis,the SBAMM scheme has better protecting rate,reducing cost of the multicast deliver tree,and so on.
