摘要: 該文研究了動態(tài)業(yè)務(wù)下,無波長變換的波分復(fù)用光傳送網(wǎng)采用固定選路時的波長分配問題,提出了一種中心式的波長分配算法-最小影響算法。該算法能精確地描述某個波長的分配對全網(wǎng)狀態(tài)的影響,因而能夠更有效地使用網(wǎng)絡(luò)資源。計算機仿真表明,如果用阻塞概率來衡量,該波長分配算法優(yōu)于文獻中已有的典型算法。Abstract: 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.
