This paper analyses current bandwidth schemes and proposes a novel dynamic bandwidth allocation scheme for EPON.
According the scheme, we define four kinds of multimedia services such as Unsolicited Request Service (URS), Realtime
Service (rt-S), Non-Real-time Service (nrt-S) and Best Effort (BE). Different kinds of services have different
Quality of Service (QoS) requirements. Our scheme considers the diverse QoS request, e.g., delay for rt-S, throughput
for nrt-S and fairness for BE. The simulation results show this novel scheme can ensure the quality of service (QoS) and
improve bandwidth utilization.
