Feedback Fuzzy Control Of Real-time And Non-real-time Network Traffic Scheduling

Real-time and non-real-time traffic control is a hot topic with the fast development of multimedia network currently and it is critical in a lot of areas.In this paper, the feed back fuzzy control has been used in the control of real-time and non-real-time network(one case in network center ,the other case in end-to-end of network), in order to get the optimal tradeoff of real-time and non-real-time traffic. And we develop the models with the fuzzy logic controller, where the fuzzy logic controller input parameters can be calculated from the state of the traffic and the history, which controlled by a slicing window. By good design of the fuzzy set and the right-setting of the parameters, we has got ideal control results which not only ensure that the lost rate of real-time is close to lowest, but also make the delay of non-real-timetraffic shorter. By using the feedback control, the system is robust in the condition of burst inputs and very sensitive to the changes of the states.
