摘要 针对WDM光网络安全生存性问题的故障的发现、定位和恢复三个重要环节之中的恢复问题,提出了一种WDM光层中的安全保护与恢复方案。采用了恢复路由选择算法和恢复波长分配算法,提出了一种混合的多层恢复机制,从而构建了一种从故障的发现、定位到故障恢复的覆盖各环节的连续性光网络安全生存机制,并在理论上进行了性能比较。 The strategy of secure survivability in WDM networks is divided into three parts:the discovery of faults,the positioning of faults and the recovery of faults.The optical signal interruption alarms analysis strategy,bit error alarms analysis strategy are used,and a method about WDM optical layer security protection and recovery is brought forth,the restoration of routing algorithm and the restoration of wavelength allocation algorithm are introduced,and the multi-layer recovery mechanisms are given.A security survivability of optical network from the discovery and positioning of faults to the positioning is advanced,which has a performance comparison in theory.The security survivability of WDM optical network is increased effectively.
