波长路由WDM光网络阻塞率的分析与计算

The Analysis of the Blocking Probability in Wavelength Routing WDM Networks

波长路由的全光网络可以在很广的范围内提供骨干网的连接并运行于极高的速度之上.对波长路由的WDM光网络引入两种分析模型,即独立模型和关联模型,分别对L跳路径的阻塞率进行了分析计算;研究了全网平均阻塞率的计算,对研究的一些结论做出了讨论.

Recent advances in WDM and optical switching make it possible to contemplate the deployment of wavelength-routing networks that will provide backbone connectivity over wide-area distances and at very high data rates. Firstly we introduces two models to analyse the blocking probability for a L-hop path in WDM networks. They are called the independence model and the correlation model. Next we compute the mean blocking probability for a whole network. At last we draw a conclusion for our study.
