A link weight assignment algorithm for traffic-engineered networks

In this paper we address issues related to the definition of effective metrics for the application of load-balancing techniques inside providers’ core networks. We will present an original approach to the problem of assigning appropriate weights to the network links. The main contribution of our work resides in having devised a solution relying on a cost function which depends on link utilization in a non-linear fashion. The paper discusses the rationale behind the choice of such a cost-function and provides some experimental results and preliminary performance analysis.
