New Approach on Reliable Restoration in MPLS Based Networks

In order to guaranty the quality of real time services on IP based networks, robust survivability with fast fault recovery and path restoration are the main goals. Many recent restoration methods spend much time for fault recovery and path restoration.MPLS based networks with connection –oriented ability can guaranty QoS by useful restoration method in short time.In this paper we proposed a new restoration mechanism base on pre-assigned end to end protection path. We apply self similar and Poisson process separately for modeling the traffic arrivals time. The comparative analysis between two models reveal the reliability growth gained through applying the proposed algorithm.
