This method is a part of a hybrid restoration ,mechanism (to be presented later), which integrates a backup-VP, method￣[2] and a distributed flooding algorithm￣[3] in theATM layer. This method is a path restoration between VP terminal nodes, completes the restoration with bi-directional message transmission by ustng pre-assigned backup VP's in case of single failure, and improvesthe restoration time of higher priority VPs in case of multi-failure, but it should cooperate with anotherorganic part of the hybrid restoration mechanism-a floodting algorithm to restore the remaining lower priorityVPs. This method can use resource more efficiently and obtain a better cost-performance feature.展开更多

This paper introduces a new restoration mechanism based on multi-layer ATM survivable network management architecture. This mechanism integrates the general control and restoration control by establishing the Working VPs logical network, Backup VPs logical network and spare logical network in order to optimally utilize the network resources while maintaining the restoration requirements.展开更多
