摘要
本文提出三种关于全光环形网络中保护信道故障的监测方法 ,即漏光法、额外业务监测法和“辅助波长”监测法 ,比较分析各自的性能后得出“升级的额外业务故障监测法”
Moniting methods of protecting channel in WDM ring network were proposed in this paper,which include leaking optical monitor,extra traffic monitor,auxiliary wavelength monitor.Comparing their performance authors can give a conclusion that update of EA monitor is a good monitor that has excellent performance and fit to random scale ring networks.
