Keywords: EPON OLT ONU User-oriented hierarchical bandwidth scheduling algorithm QoS a b s t r a c t Ethernet passive optical networks (EPONs) are being designed to deliver different quality of service (QoS) to carry heterogeneous traffic of end users. For this purpose, hierarchical scheduling is needed for upstream bandwidth allocation, with high-level(More)
In this paper, we present a new service model for aggregate scheduling. This model combines a guaranteed rate (GR) scheduler with a guaranteed rate fair aggregator (GRFA), With fair aggregation, our model can provide guaranteed services to individual flows in the presence of flow aggregation. In addition, our mode] can utilize fully the configured(More)
