A generalization of some policing mechanisms

The authors highlight the fact that most of the policing schemes proposed in the literature neglect important information on the past cell blocking behavior of the policing mechanism. They propose a modification of these schemes in which the discarded cell information is used, with almost no overhead compared to the usual strategies. The behavior of the modified policing mechanisms is discussed. This new behavior is illustrated by using the generalized leaky bucket to police the mean rate of a source. Analysis using an on/off input process shows that the modified versions detect smaller-magnitude abuses, police the sources closer to their declared resources utilization, and have a faster response time. Results are presented showing that the generalized sliding window exhibits the same kind of behavior
