| 摘 要： | 介绍一种多标签交换协议（MPLS）组播架构的实现。此种方案主要根据网络协议（IP）组播的工作原理和MPLS组播树（MMT）的管理方式,不仅可以快速的实现MPLS组播,与IP组播衔接良好,并且便于MPLS组播管理。通过IP组播路由表与MPLS层路由表建立一一映射关系,实现组播路径（M_LSP）的建立;采用上游按需分配的标签分配方式实现MPLS组播成员的加入和退出,解决了MPLS组播的扩展性问题。最终,实现基于IP组播的MPLS组播,并且通过仿真软件（OMNET＋＋）仿真实现进行验证。

| Abstract: | The construction of WPLS multicast is described.This contruction scheme,based on the working principle of IP multicast and MMT management mode,could achieve fast realization of MPLS multicast,establish a good connection to IP multicast,and is easy for the management of HPLS multicast.By upstream on-demand distribution of the label,the entrance or exist of the MPLS multicast members is realized,thus solving the expansibility of MPLS multicast,and finally,realizing the MPLS multicast based on IP multicast.This construction is verified by simulation with OMNET＋＋ simulation software. |
