Abstract :
Bursty traffic such as voice, video and graphics is supported in ATM networks and requires different quality of service (QoS). To meet the various QoS requirements of bursty traffic, a dynamic priority queue with two types of traffic is proposed and analysed. It is assumed that the traffic in each type arrives at the system according to a Markovian arrival process to describe its burstiness. The service order is determined by the queue-length-threshold scheduling policy with a Bernoulli schedule. Using the supplementary variable method, performance measures such as loss and delay are derived. Some numerical examples are presented to show the effects of the scheduling policy on the performance
