网状WDM网络的抗毁设计

Design of resilient WDM mesh networks

本文使用整数线性规划法对多光纤网状ＷＤＭ网络进行抗毁设计，使用的保护策略为共享通道保护和共享链路保护，网络设计的优化目标是使全网铺设的光纤总长度最短。然后以类ＣＥＲＮＥＴ为例，求解出不同保护策略下网络需要的光纤总长度，并分析了它们各自的特点以及波长转换对目标函数值的影响。

This paper uses Integer Linear Programming method for designing resilient WDM mesh networks. Two types of protection strategies, Shared-Path Protection and Shared-Link Protection, are used. The optimization objective is to minimize the total fiber lenght needed. CERNET is used as an example. By solving ILP models, the features of different protectinn strategies are analyzed. The influe- nce of wavelength conversion on the optimization objective is also investigated.
