摘要：MPLS is a promising technology which provides efficient routing and high speed switching. In recentyears, emerging internet applications demand for high quality of service (QoS) guarantees. This paper mainly focuseson protection of data flow over MPLS network in case of any failure occurs in node/link. Network survivability can beaffected by the faults in MPLS network. Existing approaches for fault prevalence employs global and local pathrestoration. 1) Protection Switching: An alternate path is pre-computed and pre-established before fault detected and 2)Rerouting: An alternate path is dynamically computed after fault detected, are the techniques used for fault tolerance.We are aiming towards combining the above mentioned techniques to develop a new routing algorithm to handle singleor multiple faults in MPLS network. This approach achieves less recovery time, reduced packet loss, and highthroughput.
