DELAY BOUND ANALYSIS FOR MULTIPLEXED TRAFFIC CONTROLLED BY ENHANCED LEAKY BUCKET

In ATM networks, two main functions for achieving traffic control and congestion control are Call Admission Control (CAC) and Usage Paramete r Control (UPC). Among various UPC schemes, Leaky Bucket is a popular one. In this paper, we study the characteristics of the system in whic h every traffic source is regulated by an enhanced leaky-bucket before entering the multiplexer at the edge node of the ATM network. In addi tion to the factor of mean cell rate, peak cell rate is also taken int o consideration. Based on the criteria of average waiting time at the multiplexer, wee derive the performance bounds expressed as the functi ons of the LB parameters and numbers of connections.
