摘    要:在论述IP层和光层的保护和恢复机制的基础上,提出了多层联合恢复机制的思想,针对多层联合恢复机制中各层之间如何协调进行了分析,为了获得优化的多层网络故障恢复能力,提出了利用GMPLS的基于层间协调机制的集成多层网络生存方案.

关 键 词:IP  over  WDM  多层生存性  GMPLS  生存性  IP  over  WDM  方案  网络生存  集成  协调机制  GMPLS  利用  恢复能力  网络故障  优化  分析  协调进行  思想  恢复机制  的保护  光层

Abstract:This paper presents the fundamental principles of network protection and restoration in both IP and optical layers and introduces the idea of muhilayer survivability. With regard to muhilayer survivability, analysis of the coordination between different layers is given, and in order to optimize the muhilayer restoration, a scheme of integrated multilayer survivability based on the mechanism of correspondence between layers using GMPLS has been discussed.
Keywords:IP over WDM  multilayer survivability  GMPLS
