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。
This paper designs a QoS multicast routing algorithm in IP / DWDM optical Internet. Based on evolution - simplex algorithm, a QoS multicast routing tree with limited bandwidth and delay jitter and limited error rate and cost optimization is constructed based on evolution - simplex algorithm, taking into account network load balancing. Simulation results show that this algorithm is feasible and effective, which is obviously superior to the QoS multicast routing algorithm based on traditional genetic algorithm.
