摘要:

对波分复用(WDM)全光网中的动态路由与波长分配问题进行了深入的研究,并提出了最小通道权重优先(MPWF)自适应路由与波长分配算法. MPWF设计了新的链路权重计算方法,通过整理当前链路状态和通道长度信息为业务计算路由. MPWF算法的设计既适用于波长变换网络,也适用于波长选择网络. 仿真结果显示,与一些文献中提出的自适应路由与波长分配算法相比,MPWF算法可提高网络资源的利用效率,降低业务的阻塞概率.

Abstract:

The routing and wavelength assignment (RWA) problem in WDM(wavelength division multplexing) all optical networks was studied. A novel adaptive routing and wavelength assignment algorithm, the minimum path weight first (MPWF), was proposed. Simulation result shows that compared with previously proposed RWA algorithms, the MPWF algorithm achieves better performance under uniform and non-uniform traffic models.

Key words: routing and wavelength assignment, wavelength division multiplexing, wavelength routing, all optical network
