Providing multiclass QoS in shared ATM output multiplexer

This paper proposes a mechanism for the provision of multiple classes of QoS (quality of service) in an ATM output multiplexer shared by multiple QoS classes of cell stream. First, we propose a multi-step cell class acceptance controller which controls the acceptance of the source classes based nonlinearly on the state of the queue. After that, we present a queueing analysis using the discrete time finite capacity G/D/1/B queue model and derive some important QoS measures. Finally, we discuss the implications of the work via numerical experiments
