【摘要】 光路阻塞率是智能光网络性能重要的度量指标之一。文章对影响自动交换光网络(ASON)阻塞率的因素进行了综述,对其中的两个因素:资源保留方式和波长变换器(WC)配置方式作了重点介绍。文章还应用曾用于电路交换网的基于通路图和Lee氏的计算方法近似地对阻塞率进行了计算。更多还原

【Abstract】 One of the important performance indexes in a dynamic lightpath establishment network is the lightpath blocking probability. The objective of this paper is to summarize the factors affecting the blocking probability in ASON, especially the two factors of resource reservation and wavelength converter configuration models, and presents a convenient method based on path-graph and Lee’s model to calculate blocking probability approximately, which has been used in circuit switched network.更多还原
