Abstract
Protection techniques for optical networks mainly rely on pre-allocated backup bandwidth, which may not be able to provide full protection guarantee when multiple failures occur in a network. After recovering from the previous failure, if failure occurs again, unprotected or vulnerable lightpaths cannot be recovered. In this paper, the minimal backup reprovisioning (MBR) problem is studied, in which, the node-encircling protecting cycles (NEPCs) scheme is considered for single node-failure on WDM networks. The NEPC Recovery Algorithm is proposed to recover the protecting capabilities of the NEPC. Simulation results show that the performance of the proposed method is better than that of the traditional one.
