摘要
研究了WDM环网的保护和恢复与波长分配问题,提出了一种改进的Greedy波长分配算法,仿真计算结果表明,该算法应用于WDM共享保护环(SPRING)获得了较高的波长利用率,同时本文比较了WDM环网的不同保护和恢复结构对波长资源配置的要求。
Restoration and wavelength assignment(WA) for WDM rings is discussed, and an improved greedy WA algorithm is proposed. Simulation on computer is carried out for a two-fiber WDM SPRING and the higher wavelength-efficiency is acquired by the algorithm. And the requirement of wavelength is studied and measured for different restoration configuration of two-fiber WDM rings.
