With multimedia applications, the Internet traffic increased a lot in volume, but also suffered major alterations in its nature, requesting other network services besides the current best-effort service. To satisfy this new situation, network architectures QoS-oriented such as the Integrated Services and Differentiated Services architectures have been discussed in several IETF groups. In this work we propose a methodology to implement packet schedulers, an element of fundamental importance to the new services, based on fuzzy control. The main innovation of this proposal is the employment of rule induction algorithms as C4.5 to infer the fuzzy controller’s main rules. The approach has several advantages over the current ones, specially flexibility, efficiency and the possibility of being applied in several environments.
