Dimensioning a Traffic Control Device in an ATM Network

It is well known that a single Leaky Bucket cannot control all characteristics of a source. Especially, controlling burst length and mean rate may be incompatible, while a poor control of any of these characteristics impacts directly networks performances. Given an ATM source, this paper addresses this issue and gives a general approach to choose the \best" Leaky Bucket parameters; the optimality criterion is the number of worst-case sources which the network can accomodate while ensuring the required Quality of Service.
