Abstract: This thesis presents a dynamic bandwidth management scheme for traffic on multiple MPLS paths. In our scheme we propose a utility function system to describe the relationship between end usera??s satisfaction degree and resources allocated to that user.With the QoS information brought by the utility function, admission control is first executed. After making a selection from multiple paths, a load balancing algorithm based on Gradient-Projection method is used to maximize total utility. Moreover, priority and preemption policy is also considered in our heuristic approach.Simulation results show that our scheme can dynamically manage the allocation of resources when traffic load changes, and keep QoS requirements of applications satisfied. When compared with current multiple path routing algorithms our proposed heuristic algorithm performs better in both blocking probability and total utility.
