Abstract

The Ethernet passive optical network (EPON) has recently attracted more attentions from the academic research and industry since it could be a perfect candidate for next generation access networks. Supporting differentiated services is an important issue for service providers to design an EPON system. In this paper, we propose an urgency fair queuing (UFQ) scheme to support DiffServ among multiple users in EPONs. It can achieve fairness by providing better services to best-effort users while guaranteeing the services for QoS users. The simulation results show that the UFQ scheme can effectively provide differentiated services for different classes of traffic
