Summary: 
One performance limitation of the "Leaky Bucket algorithm" for usage parameter control and traffic management in Asynchronous Transfer Mode (ATM) networks is analyzed. Simulation results show that the conventional statistical bandwidth allocation method, which uses the most bursty pattern permitted by the Leaky Bucket algorithm, can not guarantee the QOS of established Virtual Channels/Paths (VC/VP). As a result, the VC/VP bandwidth allocation method based on the Leaky Bucket algorithm is proven to be unsatisfactory.
