Abstract
In the paper, a traffic engineering enhancement to the QoS-OSPF routing protocol is proposed and used as the path selection algorithm in a DiffServ-MPLS network. The proposed scheme, TE-QOSPF, exploits the use of non-shortest paths to improve load-balancing and avoid network congestion. Simulation results show that the algorithm outperforms the QoS-OSPF scheme in terms of loss ratio, link utilisation, and delay.
