Failure handling and recovery under real-time conditions is very crucial. MPLS fast reroute was designed to meet the needs of real-time applications, such as voice over IP. Few of existing solutions handle failure based on single-link failure assumption. Few talk about multiple link failure handling but for a single service path. The proposed solution, MLNF (Simultaneous Multiple Link/Node Failure handling for different service-paths) presents a dynamic solution, which handles simultaneous multiple-link failures as well as node failure that may occur on different service paths. An algorithm and metric is proposed for optimized and prioritized backup path computation. A novel dynamic metric calculation for service path computation is also proposed. Our proposed algorithms are simulated using ns2. The simulation results show that MLNF provides an improvement over existing LDP Reroute method.
