Abstract

In this paper, we deal with the packet delay of a dynamic bandwidth allocation(DBA) scheme in an Ethernet passive optical network(EPON). We focus on the interleaved polling system with a gated service discipline. On the access side, input traffic may be aggregated from a number of users. So we assume that input packets arrive at an optical network unit(ONU) according to Poisson process. We use a continuous time queueing model in order to find the mean waiting time of an arbitrary packet. We give some numerical results to investigate the delay performances for the symmetric polling system with statistically identical stations.
