An Approach to Optimizations Links Utilization in MPLS Networks

In this paper, we present a study for the optimization of the links utilization in several MPLS network topologies. This information helps in determining the maximum link utilization required, which is a valuable knowledge in balancing load strategies in the network. We present mathematical models that tune the optimal parameters for strategically routing traffic in an MPLS network. We present the optimal link utilization model (OLUM) for different topologies. OLUM provides an approach that would result in optimally balanced link utilization. Finally we compare the results of the model with the interior point and simplex algorithms. Results show that the maximum link utilization required is minimized
