摘要
本文设计了一种 IP/DWDM 光 Internet 中的 QoS 组播路由算法。在给定用户请求的情况下,基于演化-单纯形算法构造带宽、延迟、延迟抖动与出错率受限且费用优化的 QoS 组播路由树,兼顾网络负载均衡。仿真结果表明,该算法是可行和有效的,明显优于基于传统遗传算法的 QoS 组播路由算法。
In this paper, a QoS multicast routing algorithm in IP/DWDM optical Internet is proposed. Given a user request, a bandwidth, delay, delay jitter and error rate bounded and cost optimized QoS multicast routing tree is constructed based on the evolutionary-simplex-algorithm, taking network load balancing into account. Simulation results have shown that it is not only feasible and effective but also advantageous over its counterpart based on the traditional genetic algorithm.
