Performance analysis of a fuzzy system in the policing of packetized voice sources

In this paper we analyze the performance of a policing mechanism based on Fuzzy Logic for the control of packetized voice sources. The results obtained show an excellent selectivity, close to that of an ideal policer, and a responsiveness, assessed by the combined measures of reaction time and rise time, which is decidedly better than that of the Leaky Bucket. Analysis by simulation also shows that the fuzzy policer is efficient in the combined control of two traffic descriptors, the Sustainable Cell Rate and the long-term Average Cell Rate.
