摘要
提出了一种新的基于业务等级的WDM波长分配算法-MIT(最小影响门限法),并采用三种网络拓扑,在不同负载的动态业务下对所提算法进行了研究,仿真结果表明该算法既满足了上层业务不同QoS需要,同时又充分利用了有限的网络资源,使全网的平均阻塞率降低。
In this paper, a novel priority-based wavelength assignment algorithm, Minimum Influence Threshold Method is proposed. Through simulation in three representative network topologies under different dynamic traffic loads,the results show that the method can not only meet the different QoS requirements of the client layer service, but also utilize the finite networking resources efficiently with reduced blocking probability.
