Abstract :
Future broadband access networks are expected to rely more and more on fiber-based solutions. To this end PON networks are regarded as one of the most prominent alternatives. This paper proposes a novel MAC scheduling algorithm for GPON networks that can offer efficient operation, combining QoS differentiation with high network utilization. It achieves improved performance by making use of both fixed and dynamic bandwidth allocations along with predictive allocations and the novel concept of offset-based scheduling with flexible intervals, being thus able to effectively adapt to fluctuations of traffic and meet quality of service requirements. The concept of operation is described in detail and the system performance is evaluated using computer simulation.
