The proposed methods have been designed to handle single fault based on the protection switching and rerouting techniques. In this paper three algorithms are developed for fault recovery in the MPLS network based on ingress LSR, alert LSR and core LSR. The proposed methods have been simulated using the Network Simulator (NS2) and the simulation results show that the proposed methods significantly improve the network performance in comparison to similar existing methods.

The occurrence fault at link degrades the network performance due to data packets loss. This paper proposes an efficient model for rerouting traffic in MPLS network when a single and multi-fault occur in working link based on the protection switching and rerouting algorithms. In this model three algorithms are developed for fast fault recovery in MPLS network based on ingress LSR, alert LSR and core LSR. The proposed model has been simulated using Network Simulator (NS2) version 2.34, simulation results show that the proposed model significantly improves the network performance such that eliminates packet disorder, reduces the packets loss, get better PDR, decreases end to end delay and enhance throughput. The proposed model has less space complexity compared to other methods that reached to 13.33% in single fault and 33.33% in multi-fault and has a fast recovery time compared to other methods.

The method has been designed to handle both single and multiple faults based on the protection switching and rerouting techniques. The proposed method leads to less packets loss, has better Packet Delivery Ratio (PDR), good throughput and eliminates packet disorder. The proposed method has been simulated using the Network Simulator (NS2) version 2.34 and the simulation results have shown that the proposed method significantly improves the network performance in comparison to similar existing methods.
