Otimização de Controlador Fuzzy para Provisionamento de Recursos em Ambiente DiffServ através de Algoritmo Genético

Marcial Porto FernandezAloysio de Castro P. PedrozaJosé Ferreira de Rezende

The majority of work in the Differentiated Services (DiffServ) area handles Quality of Service (QoS) guarantees on a per node basis, assuming this provides QoS in the whole domain. But it could fail with data flow aggregation. Then, provisioning techniques should be used to reconfigure node parameters according traffic changes. We showed a proposal to use a fuzzy controller that reconfigures all DS nodes according to ingress traffic. This paper proposes a methodology to choose the best fuzzy controller parameters using the Wang-Mendel and a genetic algorithm to achieve the desired QoS. The functionality of a prototype are demonstrated by simulation of a voice over IP application in a DiffServ domain.
