Abstract
This paper presents a contribution for the development of network management tools able to
automatically provide QoS aware routing configurations. In this perspective, a traffic engineering
framework able to provide near-optimal OSPF configurations is presented. The devised solution
takes into account the multiconstrained QoS demands of a given network domain in order to
improve the quality of the OSPF weight setting process. To pursue this objective, this work resorts to
Evolutionary Algorithms, which provide OSPF configurations based on a bi-objective function. The
proof of concept of the proposed optimization framework resorts to a wide range of simulation
studies, clearly showing the effectiveness of the devised mechanisms.
