基于改进蚁群算法的WDM光网络恢复优化

针对WDM光网络的恢复,提出一种基于蚁群算法(ACA)的WDM光网络恢复优化算法,算法以WDM光网络的虚拓扑为主要研究对象,模拟蚂蚁寻址方式获得网络业务受损节点恢复方案.在优化过程中,结合免疫算法的变异操作对全局业务分配进行自适应调节,以获得更高的故障恢复率水平,最终实现网络受损业务恢复,使整个网络资源利用率达到最优.仿真结果表明,该算法可满足较高的恢复率需求情况,并可应用于任意形式WDM网络拓扑结构.

Restoration sptimization of WDM optical networks based on improved ant colony algorithm

This paper proposed a new algorithm based on ant colony algorithm for WDM optical network restoration optimization.Aim to design the virtual topology,we get the solutions by simulating the addressing mode of ants,and moreover,use the aberrance operation of immune algorithm to adjust the global traffic distribution. Finally,we accomplish the global optimization of the virtual topology and traffic restoration,maximize the resource utilization.The result shows the algorithm can satisfy high restoration ratio d...
