| 摘 要： | 为了解决波分复用(WDM)网络中由于流量分布变化而导致网络中预配置P圈保护资源分配不准确的问题,提出了可重构P圈的概念,并建立了一种基于网络性能参数进行重新配置的P圈模型.在OPNET中搭建仿真平台,基于泛欧COST239网络拓扑结构,对提出的模型进行了验证.仿真结果表明,根据网络的变化重新计算优选P圈,可以降低网络的性能抖动,提高网络的保护资源利用率.

| Abstract: | In order to avoid inaccuracies in the pre-configured P-cycle protection resource allocation arising from the variations of the traffic distribution in WDM networks,a reconfigured P-cycle concept is proposed and a reconfigured P-cycle model based on network performance parameters set up.A simulation platform is constructed in OPNET to verify its efficiency on the basis of Pan-European COST239 network topology.Simulation results show that re-computing the optimized P-cycle according to the network variation c... |
