提出了一个有效的 Qo S组播路由机制 ,基本思想是使路由器只存储其两层邻居节点的可达性信息以及链路的 Qo S状态信息 ,以减少路由器存储开销 ,提高协议的规模伸缩性 (Scalability) .协议采用受限的泛播技术 ,构造了一个接受节点发起的、采用多路径技术的、分布式路由算法 .文章描述了协议的数据结构、组播树的构造算法 ,分析了协议的性能并给出了模拟实验结果 ,表明基于受限泛播技术的组播路由协议具有节点存储开销小、呼叫接收成功率高、易于实现等特点 .
An effective Qo S multicast routing mechanism is proposed. The basic idea is to make the router store only the reachability information of its two neighbors and the Qo S status information of the link so as to reduce the storage overhead of the router and improve the scalability of the protocol (Scalability) .The protocol uses limited pan-broadcast technology and constructs a node-initiated distributed routing algorithm that uses multipath technology.This paper describes the data structure of the protocol, the construction algorithm of the multicast tree, analyzes the protocol The simulation results show that the multicast routing protocol based on limited pan-broadcast technology has the advantages of low storage overhead, high success rate of call reception and easy implementation.
