MPLS is a promising technology which provides efficient routing and high speed switching. In recent years, emerging internet applications demand for high Quality of Service (QoS) guarantees. This paper mainly focuses on protection of data flow over MPLS network in case of any failure occurs in node/link. Network survivability can be affected by the faults in MPLS network. Existing approaches for fault prevalence employs global and local path restoration. Protection switching: an alternate path is pre-computed and pre-established before fault detected and rerouting: an alternate path is dynamically computed after fault detected, are the techniques used for fault tolerance.
