MPLS network as IP backbone has capacity constraint and routing mechanism constraint. The latest constraint, which based On Shortest Path First scheme (OSPF), results in best-shortest calculated path. This scheme produces resource with unfair consumed. Some subsets of network may get congested while others remain free. As a consequence, the new routing management scheme is proposed using Minimum Interference Routing Algorithm (MIRA). MIRA puts higher priority on some ingress egress pair according to SLA of some traffic. This new method covers critical links in the network. The critical links identifiedin3 ways: Critical Links based on Maxflow, Critical Links based on Threshold, and the Enhancement of Critical Links based on Threshold.
