A Load Balancing Scheme for Congestion Control in MPLS Networks

In this paper we develop a Load Balancing scheme for networks based on the MPLS framework. The proposed al-gorithm (DYLBA- Dynamic Load Balancing Algorithm) im-plements a local search technique where the basic move is the modification of the route for a single Label Switched Path. Experiments under a dynamic traffic scenario show a reduced rejection probability especially with long-lived connection requests, thus providing a better use of re-sources when compared to existing constraint-based rout-ing schemes for traffic engineering in MPLS networks
