| 摘 要： | 提出了一种新的基于多协议标签交换组播的局部标签聚合方法,通过查找入口标签边缘路由器中保存的节点表,得到与已有组播树具有最大匹配的组播子树.在此组播子树上,因为不同的组播会话具有相同的路由,可给这些组播会话分配相同的标签,而不需要整个组播树的完全匹配.通过性能分析表明,可进一步减少网络中的标签数量,有效的提高扩展性和可靠性等网络性能.

| Abstract: | In this paper,a novel scheme of partial label aggregation based on MPLS multicast is proposed,which gets the multicast subtree matched existing multicast tree by searching branch node table in ingress LER.On the subtree,we can assign the same label to differ the multicast sessions and needn't match the whole multicast tree because they have the same route.The performance analysis indicates that the number of label in network could be cut down and the scalability and reliability could be enhanced. |
