Abstract
The Ethernet passive optical network (EPON) is a reliable cost effective,
high bit-rate point-to-multipoint optical access network. With new applications
and services that emerged in last decade, the quality of service support in
EPON has become a major concern. In our work, we analyze the performance of
dynamic bandwidth allocation algorithms and intra-ONU scheduling algorithms,
and further investigate how a combination these algorithms can be implemented
in EPON in order to efficiently support the transmission of multimedia traffic
and improve the performance of the low priority traffic at the same time.
The system model separates the transmission of high priority traffic from
the transmission of lower priority traffic and introduces the implementation
of intra-ONU scheduling algorithms for lower traffic class transmission. Numerical
results show a slight degradation of transmission characteristics for high
priority traffic but on the other side, significant improvement of the lower
priority traffic transmission parameters has been detected.
