Analysis of a multi-server queueing model of ABR
In this paper we present a queueing model for the performance a-na-ly-sis of ABR traffic in ATM networks. We consider a multi-channel service station with two types of customers, the first having preemptive priority over the second. The arrivals occur according to two independent Poisson processes and the service times are assumed to be exponentially distributed. Each type-1 customer requires a single server, whereas type-2 customers are served in processor sharing fashion. We give a complete characterization of the joint distribution of the numbers of customers (of both types) in the system in steady state. Numerical results illustrate the effect of the high priority traffic on the service performance of the low priority traffic.
