WDM光网络中的共享通道保护方法

Shared Channel Protection in All Optical WDM Networks

本文提出了全光网中提高资源利用率的共享保护方法 ,并把此方法与专用的预选路由保护方法做了比较 ,此外 ,从光纤数 ,波长数 ,业务强度 ,共享程度和拓朴结构对该保护方法做了详细的分析 .结论表明共享保护通道可以极大提高网络的性能 ,使得网络阻塞率减低 。

A share protection method was proposed in all-optical networks, and compared with pre-routing protection method in the number of fiber and wavelength, traffic intensity, share degree and topology. The result is that the share channel protection can improve the performance of network, decrease the network blocking ratio and enhance the network utilization.
