A Planning and Adaptive Routing Methodology for Multimedia Networks

This work presents a traffic engineering proposal based on a network planning and adaptive routing strategy for multimedia networks. The proposal uses a hybrid traffic model based on fBm (fractional Brownian motion) and Markovian processes to characterize the multimedia traffic and calculate QoS metrics and effective bandwidth. The routing strategy was evaluated in a scenario with different Poisson and self-similar aggregated traffic series. The results show that the proposed methodoly achieves the established QoS requirements and promotes a better load balancing in the network.
