Analysis of the blocking probability in WDM networks with sparse wavelength conversion

本文主要对具有稀疏波长变换的WDM全光网的阻塞率进行分析,首先提出一种模型分析了无波长变换器的L跳路径端到端阻塞率,接着对部分波长变换器的L跳路径的阻塞率进行求解,随后分析了全网的平均阻塞率。研究得到的主要结论是,波长变换器使用的有效性取决于网络的连接度。

This paper analyzed the blocking probability in Wavelength Division Multiplex （WDM） networks with sparse wavelength conversion. Firstly, we introduced a model to analyze the blocking probability for an L-hop path without Wavelength Converter （WC）. Secondly, we analyzed the sparse wavelength conversion case, and then we computed the mean blocking probability for a whole network. A conclusion for our study is that efficiency of improved blocking probability with WC correlate to network link mode.
