| 摘 要： | 维护多播信息需要额外的硬件开销,多播体系结构缺乏可扩展性,限制了多播业务的发展。本文在多播中应用MPLS最小冲突路径算法,在分支节点的MPLS中加入多播信息表,实现基于源树的多播树构建,从而解决了MPLS多播中数据转发的标签分配问题,具有良好的扩展性。实验表明,利用MPLS最小冲突路径算法,起到了节约带宽和提高多播性能的作用。

| Abstract: | Maintaining multicast information needs additional hardware overhead,and making the multicast architecture lacks scalability,thus limiting the development of multicast services. This paper applies a least interference path algorithm for MPLS in the multicast,adds multicast information table in the branch nodes MPLS,and implements the source-tree multicast over MPLS,so it is able to solve the difficulties of label distribution on data transmission in the MPLS multicast to achieve a good scalability. The simu... |
