This paper introduces an end-to-end QoS scheme for GPON access networks, which consists of an intra-ONU dynamic weighted fair queuing (DWFQ) scheduler and a multiservice dynamic bandwidth allocation algorithm(MDBA). Both DWFQ and MDBA are integrated in DWFQ-MDBA scheme to support proportional differentiated services (PDiff-Serv) while alleviating the problem of light-loaded penalty resulting from intra-ONU strict priority scheduling employed in GPON access networks. We conduct detailed simulation experiments using our developed Java-based simulator to study the performance and validate the effectiveness of the proposed DWFQ-MDBA scheme in terms of the average packet delay and utilization.
