Abstract

In this paper, a multiobjective optimization QoS-aware path selection algorithm is proposed for LSPs setup in DiffServ-MPLS networks. We simultaneously optimize multiple QoS objectives by a genetic algorithm in conjunction with concept of Pareto dominance. Simulation demonstrates that the proposed algorithm is capable of discovering a set of QoS-aware near optimal paths within in a few iterations. In addition, simulation results also very promising indicates scalability of the algorithm with increasing number of network nodes.
