Controle dinâmico de QoS baseado em políticas

— Converged IP-based networks and services, as well the huge increase in IP traffic along the last few years, have revealed the need for new dynamic mechanisms capable of handling all types of IP-based multimedia traffic. This work proposes a solution based on control theory running on a DiffServ domain. Other than classical solutions, whose objective is to provide strong QoS responses only for one or two premium classes, our proposal aims to provide QoS for both isochronous and best-effort applications. The results presented here show that our objective is accomplished with the correct fitting of the WFQ parameters without overestimating their weights.
