Fuzzy service scheduling scheme in ATM networks

A service scheduling scheme is to control the order of servicing cells within an ATM node and maintain their Quality of Service (QoS). Recent researchers have focused on the efficient ways of isolation among different incoming traffic, or the different approach to improve the overall QoS. However, they seldom try to achieve both objectives simultaneously. In this paper, we propose a new service scheduling scheme with fuzzy logic design to achieve these two goals. We use a fuzzy controller to choose an appropriate service scheduling scheme from the two traditional methods for the current input traffic environment. Numerical results show that this approach not only can achieve both objectives, but also show better performance as compared with traditional methods.
