无光缓存多波长光交换的阻塞性能分析
Analysis of blocking performance of the multi-wavelength optical switching without optical buffer
【摘要】 文章分析了多波长光交换在无光缓存条件下节点的阻塞性能,也分析了不同交换网络规模下多链路共享的阻塞性能,提出了加权偏转交换方式,利用网络的空闲交换容量,疏导业务负荷,以进一步降低阻塞率.
【Abstract】 The blocking performance of the multiwavelength optical switching node without optical buffer, as well as the node blocking performance of shared multilink in different networking scales are analyzed in this paper. A novel weighted deflectionswitching mode is proposed; it utilized the extra idle switching capacity to groom the traffic load, so the blocking ratio will be reduced further.
