摘要

WDM网络将在未来的骨干网中扮演重要的角色

具备抗毁能力和支持多优先级都很必要.本文提出了两种基于优先级的波长分配算法——波长编号法和分配限额法

并研究了动态业务下

抗毁WDM网络使用这两种波长分配方法后网络的阻塞率性能.研究的内容包括业务量负载、光纤链路的波长通道数和每条链路包含的光纤数对网络性能的影响.本文还给出了仿真结果.

Abstract

WDM Network will play important role in future backbone networks.It is necessary that WDM networks have the capability against component failure and support multi-priority.Two priority-based wavelength assignment methods

Wavelength Number Method and Assignment Quota Method

are proposed in this paper.We study network performance when these wavelength assignment methods are used for survivable WDM network in dynamic traffic pattern.Contents include influences on blocking probability from traffic load

total number of available wavelength channels per link

and the number of fibers per link.Simulation results are also given in the paper.
