The fuzzy leaky bucket for policing mechanism in ATM networks

This paper presents a model of fuzzy leaky bucket (FLB) for policing mechanism (PM) in ATM networks. Because of the fundamental contract, call acceptance control (CAC) may not be reasonable and some traffic is very difficult to model, thus dynamic adjustment is needed during practical applications. We have presented the function and theory of the designed FLB. The conclusions show that the FLB is a better dynamic method of PM than the conventional one. The cell loss probability and mean time delay are lowered and the utilization of bandwidth is improved in the FLB.
