摘要

本文在层次化网络结构多播路由算法的基础上

提出一种改进的多播数据包拆分机制

并设计实现出多播片上网络.该机制针对目的节点为上行路径上以及上行路径相邻节点的情况

采用空闲拆分策略

在不引入新的死锁情况下

有效降低了多播数据包的整体延迟.实验分析表明

该拆分机制在目的节点在上行路径及其邻域数量多时表现更加优越.相对于不拆分传输方式

传输延迟最大降低了50.3%.

Abstract

This paper proposes an improved multicast packet split mechanism based on the multicast routing algorithm of hierarchical network structure; this paper designs and implements the multicast network.This mechanism effectively reduces the overall delay of multicast packets without introducing new deadlocks when the destination node is the upstream node and the neighboring nodes in the upstream path.The experimental results show that the proposed method is superior to the destination node in the upstream path and its neighborhood.The transmission delay is reduced by 50.3%

as opposed to no split transmission.
