Abstract

In this paper is introduced a FSC (Fuzzy Service Classification) algorithm. The algorithm adaptively changes weight coefficients that determine the amount of allowed bandwidth for each service class in the outputs of routers. New weight coefficients are calculated periodically on routers. The proposed fuzzy model simplifies the link sharing to two service classes: one for UDP and another for TCP. It is shown through simulations that the fuzzy model is more stable and reacts faster to different traffic states than the traditional WFQ (weighted fair queueing) scheduler.
