摘要
多粒度光网络(MGON)的生存性问题中增加了波带失效的故障类型,需要考虑和制定基于波带通道进行故障恢复的生存性策略。针对MGON中的节点失效提出了一种改进的基于GMPLS的共享备份恢复策略(GSR),采用故障链路源节点进行差异化恢复和共享备份恢复策略,可以减少因预留资源导致的成本。
Survivability issue in multi-granularity optical network (MGON) introduced bandpath failure type which should be considered into the whole survivability strategy. This paper presents an improved GMPLS sharing recovery strategy (GSR) to deal with node failure in MGONs. Differentiated restoration schemes in source node and shared backup resources strategy can reduce cost due to backup resource reservations.
