光交换通信网络路由与波长分配研究

Study on routing wand avelength assignment for optical networks

本文采用了作者提出的Lagrange松弛框架下子问题序贯求解的新方法,解决了具有大量 相同连接的路由与波长分配问题,大大改善了对偶解质量。数值计算验证了新方法的有效性。

A new method developed by the authors, Anew method within Lagrangian relaxation framework is presented to solve the routing and wavelength assignment problems. The quality of the dual solution can be greatly improved. Numerical testing results verify the effectiveness of the new method.
