摘要 该文研究了动态业务下,无波长变换的波分复用光传送网采用固定选路时的波长分配问题,提出了一种中心式的波长分配算法-最小影响算法。该算法能精确地描述某个波长的分配对全网状态的影响,因而能够更有效地使用网络资源。计算机仿真表明,如果用阻塞概率来衡量,该波长分配算法优于文献中已有的典型算法。 In this paper, a heuristic algorithm-least efFect (LE) algorithm is proposed for the dynamic centralized wavelength assignment problem in fixed-routing wavelength division multiplexing (WDM) networks without wavelength conversion. Compared with the previously proposed algorithms, LE algorithm can modei the effect of wavelength assignment on the net-work more accurately. Simulation results show that LE algorithm performs better than those algorithms in the most cases.
