摘要：Survivability is the capability of a network to maintain service continuity in the presence of faults within the network. In this paper, we presented the new survivability method and discussed the capability of survivability in optical network. The survivability in WDM networks is implemented using protection and restoration techniques. Protection is a static mechanism to protect against failure, where the resource for both the primary and the backup light-paths are reserved prior to the data communication. Restoration on the other hand, is a dynamic mechanism where the backup light-path is not set up until the failure occurs. Survivability using these techniques is usually provided to handle single link failures in the core network..
