An Efficient Routing Method for Protection Data Flow in the MPLS Network

This paper presents an efficient method for rerouting traffic in the Multiprotocol Label Switching (MPLS) network, when a fault occurs in the working link. 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.
