Abstract
Multi Protocol Label Switching (MPLS) has become an important technology for Internet Service Providers (ISPs). MPLS features provide flexible traffic engineering solutions and Quality of Service (QoS) support for high priority traffic. This has resulted in an increasing interest in MPLS reliability for providing efficient restoration with guaranteed QoS. In this paper, we propose constraint based local path restoration technique in MPLS called ConstraintBased Label Switched Path (LSP) Handover(CBLH) to dynamically reroute traffic around a failure or congestion in an LSP. The proposed scheme reduces the restoration time by QoS based Forward Equivalence Class (FEC), LSP classification and satisfies the traffic constraints like delay, packet loss and utilization for different Class of Service (CoS). Through simulation, the performance of the proposed scheme is measured and compared with existing schemes.
