A New Fuzzy Policing Algorithm for Traffic Control in ATM Networks

The used parameters for present traffic control in ATM network are fixed and inflexible. In order to overcome these shortcomings, a new fuzzy policing algorithm is presented, and the suitable fuzzy control rules are given. The policing parameters with better dynamical and self-adaptive control performances are efficiently adjusted based on the traffic parameters by the new algorithm. The results of computer simulations show that the new fuzzy policing algorithm is superior to the simple leaky bucket mechanism in lowering cell loss probability, improving the response speed for the burst traffics, raising the utilization efficiency of network resources and so on. Good effects of the new algorithm are also proved on the present traffics in ATM network. The new fuzzy policing algorithm may be widely applied in performance improvements and evaluations of ATM and other networks. Thus, it is important and valuable in theoretical studies and actual applications.
