V. Catania et al., A COMPARATIVE-ANALYSIS OF FUZZY VERSUS CONVENTIONAL POLICING MECHANISMS FOR ATM NETWORKS, IEEE/ACM transactions on networking, 4(3), 1996, pp. 449-459
In ATM networks, usage parameter control is required in order to ensur
e that each source conforms to its negotiated parameters. To this purp
ose, several policing methods, such as leaky bucket and window mechani
sms, have been introduced in literature. However, traditional methods
have proved to be inefficient in coping with the conflicting requireme
nts of ideal policing, that is, a low false alarm probability and high
responsiveness. This led us to explore alternative solutions based on
artificial intelligence techniques, specifically, in the field of fuz
zy systems, In this paper, we propose a policing mechanism based on fu
zzy logic that aims at detecting violations of the parameters negotiat
ed. The main characteristics of the proposed fuzzy policer are simplic
ity and the capacity to combine a high degree of responsiveness with a
selectivity close to that of an ideal policer. Moreover, it can easil
y be implemented in hardware, thus, enhancing both cost and processing
performance. The reported simulation results show that the performanc
e of our fuzzy policer is much better than that of conventional polici
ng mechanisms.
