Abstract:
A method for monitoring and controlling the sustainable cell rate of a connection in ATM networks using a leaky bucket mechanism, said leaky bucket mechanism including a leaky bucket whose real-valued content drains out at a drain rate but is increased by an increment for each conforming cell, said method comprising the steps of:receiving a cell from said connection; determining whether the received cell in the previous step is conforming in accordance with the content of said leaky bucket and a threshold; and updating said leaky bucket according to the determination of the previous step, wherein the content of said leaky bucket is added by a dynamically adjustable increment when said received cell is a conforming cell, a value of said dynamically adjustable increment being provided by fuzzy logic, said fuzzy logic monitoring a long-term mean cell rate and a short-term mean cell rate of said connection and then using a set of linguistic rules.
