摘要
文章提出一种基于指定信源的协议无关组播(Protocol Independent Multicast-Source Specific Multicast,PIM-SSM)协议的多协议标签交换虚拟专用网(MPLS VPN)组播算法,该算法利用处于分支点的核心路由器才需要维护组播表和复制组播数据的特点,在MPLS VPN中引入了组播管理点来更好地实现组播。文章描述了算法的具体细节和实现原理,评价了该算法的可行性和优越性。
This paper presents a new multicast algorithm based on Protocol Independent Multicast-Source Specific Multicast(PIM-SSM)for MPLS VPN.Utilizing the theory that only the branching core routers need to maintain the multicast routing-table and copy the multicast data,this algorithm introduces multicast managers into MPLS VPN to better implement multicast.This paper describes its specific details and implementation principle and evaluates its feasibility and advantages.
