A Resource Efficient Fast Recovery Strategy for Survivable WDM Networks
Abstract: ABSTRACT In WDM networks when failure occurs, huge amount of data is lost in a fraction of second. Therefore, the failed connection request must be re-routed through backup route as soon as possible. For achieving fast connection recovery, the primary lightpath is either link or segmented protected. However, the strategies result in inefficient utilization of resources. In this paper, we present a resource efficient parallel signaling-shared path protection (PS-SPP) based …
