基于最小化波长需求的波长路由光网的优化设计

Optimal Design of Wavelength-routed Optical Network Based on Minimizing Wavelength Requirement

讨论了波长路由光网的资源优化设计问题。提出了一种新的整数线性规划(ILP)公式 ,用于解决波长通道 (WP)和虚波长通道 (VWP)的路由选择和波长分配问题 ,它的优化目标是最小化网络需求。以中国高速信息示范网 (CAINONET)为例 ,分析了波长通道 (WP)和虚波长通道 (VWP)路由方案之间在波长需求方面的差别。同时还研究了网络波长重用度的问题。

The optimal design of wavelength routed optical networks is discussed. New integer linear program(ILP)formulations are proposed for routing and wavelength assignment of wavelength path(WP)and virtual wavelength path(VWP)Routing scheme, the objective function is to minimize the required number of wavelengths. The difference in wavelength requirements between WP and VWP routing scheme is analyzed by taking China Information and Optical Network(CAINONET) as the example. The wavelength reusability is also investigated.
