A Queueing Model with Applications to ATM and DQDB

概要

In this work, we formulate and solve a discrete-time queueing problem that has two potential applications: ATM multiplexers and DQDB networks. We first consider the modeling of an ATM multiplexer. The object of analysis is a periodic traffic stream(CBR traffic), which is one of the inputs to the multiplexer. As in previous works of the subject, we consider a memoryless background traffic input. Here, in addition to this background traffic, we take into account the influence of a high-priority traffic, which is time-correlated and requires expedited service. We analyze the influence of these two type of traffic on the statistics of the interdeparture time (jitter process) and the delay of the periodic traffic stream. Our results show that the delay and jitter are very sensitive to the burstiness of the high priority traffic arrival process. We next apply our analytical modeling to a DQDB network when some of its stations are driven by CBR sources and use the Guaranteed Bandwidth(GBW) protocol. We can obtain interesting results concerning the influence of the physical location of a DQDB station on the jitter.
