Abstract :
The performance limitation of the “leaky bucket algorithm” is analyzed for usage parameter control and traffic management in asynchronous transfer mode (ATM) networks. Simulation results show that the conventional statistical bandwidth allocation method, which uses “the worst pattern derived from the cell interarrival time moments” permitted by the leaky bucket algorithm, can not guarantee the quality of service (QOS). As a result, this paper proves that the VC/VP bandwidth allocation method based on the leaky bucket algorithm is unsatisfactory
