摘要: 提出了一种可扩展性较好的基于MPLS的稀疏模式的IP组播算法,利用分枝节点和隧道相结合的原理,实现了共享树的组播。通过使用隧道技术,实现多点到多点的MPLS共享树组播,解决了MPLS组播中的关键问题:mp2mp的标签分配。基于网络仿真软件NS-2,实现了该算法的仿真模块。实验证明,该算法是可行和有效的。

Abstract: This paper designs a scalable MPLS sparse-mode multicast algorithm. With tunneling technology and non-branching nodes technology, the algorithm implements shared-tree multicast over MPLS. Using tunneling technology to implement multipoint-to-multipoint shared-tree multicast can solve one of the difficulties of MPLS multicast: mp2mp label distribution. The paper also introduces the implementation of the MPLS shared-tree multicast in NS-2 and analyses some simulated outcomes.

Key words: MPLS, IP multicast, MPLS multicast, scalability, tunneling, non-branching node
