一种波长路由全光网络优化设计及应用

研究了环网结构的波分复用（wavelength division multiplexing, WDM）全光网中的波长路由分配问题，以波长数量最小化为优化目标，提出了一种基于构造环的波长路由分配启发式算法.经过进一步优化，算法适用于环网、环带链、多环、格状网等结构；还可用于统一业务模式，甚至可以延伸到任意的业务模式情况，具有很好的通用性.应用结果表明，该算法可以使网络所需波长数目等于或接近最优解.

Optimal design and application in wavelength-routed all-optical networks

For resolving routing and wavelength assignment (RWA) problem in all-optical networks (AON), a novel wavelength allocation algorithm based on circle constructioo was proposed. The optimal objective was to minimize the number of all wavelenguhs. Analysis showed that the algorithm has a more general purpose and can be used in most common networks such as ring, multi-rings and mesh network, and arbitrary traffic model. Applications show that the algorithm can yield or closely approach the optimum solution.
