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.
