摘 要：正Since the survivability becomes more and more important in WDM backbone network design, the signaling strategy corresponding to a protection/restoration scenario upon failures will Influence the performance and then determine the integrity of the total solution. In this paper we will discuss control mechanisms for several representative protection schemes, analyze their adaptation and application, and propose the corresponding to control protocol signaling model and control protocol for a novel dynamic group protection strategy. The simulation results show that the coatrol overhead of our proposed method outperforms the segmented protection and has the benefit on resource utilization and failure restoration speed.
