摘要
在分析了网络中基于延时和带宽受限的组播路由优化问题的基础上 ,本文提出了一种新的启发式算法 ,并进行了实验和分析 .结果表明文中构造的路由方案成功地解决了当网络中存在多组组播业务时的QoS路由选择问题 .此方案不仅保证了带宽、端到端延时 ,优化了路由树的代价 。
On the basis of describing the optimization of multicast routing with delay and bandwidth constrained,the paper presents a new heuristic algorithm.Then some exp eriments have been given to analyze the performances.The result shows that the r outing mechanism in this paper successfully solves the QoS routing problems when many-to?any cast session exists.The scheme not only optimizes the routing tr ee with guarantee of the bandwidth and end to end delay,but also effectively con trols the algorithm complexity which is suitable for large size of network.
