【摘要】 提出了一种在非精确网络状态信息下满足时延和带宽约束的最小代价组播路由算法。基于非精确网络下门限更新策略,提出一种将安全性和组播树代价相结合的路径选择函数。模拟多组播业务的仿真结果表明,该算法所得组播树的代价最优,而且请求接受率较高,反映了该算法同时具有较好的QoS能力和负载均衡能力。更多还原

【Abstract】 A delay and bandwidth constrained least-cost multicast routing algorithm with imprecise state information is proposed. Under threshold based link state update policy, this algorithm presents a new path- selection function which combines the safety and cost of a path. The simulation results for multi-service request show that the cost of multicast routing tree is the best and the accepting rate of request is also better, therefore, this algorithm is efficient in both QoS and balancing network load.更多还原
