The issue addressed by the project is to offer a network infrastructure that is adapted to the current traffic profile for the service to be used with the expected quality. In particular, the cases will be considered in which the traffic profile is not supported by the infrastructure, or that it is overloaded. In this case, the choice of new links is very important to adapt the network to the traffic profile. However where the links will be inserted is the challenge addressed in this paper. The bandwidth and the paths average length were analyzed.
