Abstract

In this paper, we investigate the mean packet delay of a dynamic bandwidth allocation(DBA) scheme in an Ethernet passive optical network(EPON). We focus on the interleaved polling algorithm with a gated service discipline and two stage queues. We assume that input packets arrive at an optical network unit(ONU) according to a Poisson process from several types of users. We use a continuous time queueing model in order to find the mean waiting time and cycle time of an arbitrary packet. We give some numerical results to investigate the delay performances for the symmetric polling system with statistically identical stations.
