abstract = {The use of passive
optical networks
(PONs) enables access rates of multi-Gbit/sec bandwidth and provision of quality
of service for high definition multimedia services.
In this paper, we consider and analyse a generic
multi-priority dynamic bandwidth allocation (DBA)
algorithm for TDM PONs
serving multimedia traffic in an upstream link. PON traffic is served strictly
according to its priority. We consider this DBA
algorithm using two approaches: (i) the algorithm assigns
a fixed service quantum to each priority
service and (ii) different service quanta are assigned to different
priority services. The mean message delay is
evaluated using a multiqueue
processor sharing (MPS)
model and an MPS with Heterogeneous Traffic
(MPS-HT)model for the
two approaches respectively. The MPS model is
a classical processor
sharing model limited
by the critical assumption that there is egalitarian service
sharing among all users, which is inefficient
for multimedia applications in PONs. We extend the
MPS model to a general
MPS-HT model that enables the analysis of message
delay performance in the case where the service quanta may be different
for different services.}
