A major problem on the current networks is that the preferred routes tend to converge to paths of greater capacity. This decision causes a waste of resources in a way that there is much traffic in few links. It occurs because the IGP protocols always take the lowest cost path from the origin to a destination. However, the lowest cost path is not always the fastest or the less congested. On this paper, we propose the utilization of one of the main services of MPLS, the use of Traffic Engineering. It becomes indispensable for optimizing the use of the network, allowing to obtain as much as it is possible of the existing infrastructure or to treat an unexpected congestion (any event which drastically changes the traffic pattern). With MPLS TE (Traffic Engineering) we can create tunnels to remove part of the congested link traffic, redirecting it to non-congested paths.
