Abstract

This work presents a methodology for network traffic engineering based on a hybrid traffic model and an adaptive routing algorithm. The hybrid traffic model pursuits the calculation of more accurate Qos metrics and effective bandwidth for multimedia traffic in order to optimize the sizing of network elements at a minimal cost. During network operation, the links weighted values are modified to compute shortest path routing algorithms in an adaptive manner to comply with the traffic effective bandwidth and QoS requirements. The network routing methodology was evaluated in a network topology that aggregates different traffic types, Poisson and self-similar. The results show that the proposed methodology achieves the QoS requirements and promotes a more efficient traffic balancing within the network.
