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 resource optimization design of wavelength routing optical network is discussed. A new integer linear programming (ILP) formula is proposed to solve the routing and wavelength assignment problems of wavelength channel (WP) and virtual wavelength channel (VWP). Its optimization goal is to minimize the network requirements. Taking CAINONET as an example, this paper analyzes the differences in wavelength requirements between wavelength channel (WP) and virtual wavelength channel (VWP) routing schemes. At the same time also studied the problem of network wavelength reuse.
