8 February 2005 A hierarchical weighted bandwidth guaranteed scheme for QoS management over EPON
Author Affiliations +
As a promising solution for the next generation broadband access network, Ethernet passive optical networks (EPONs) are being designed to deliver multiple services and applications, such as voice communications, video conferencing, real-time transactions and new evolving bandwidth-consuming applications. To support these applications with their various requirements, Quality-of-Service (QoS) management over EPON is required. In this study, we present a novel scheduling scheme, hierarchical weighted bandwidth guaranteed (HWBG) scheme, which could effectively support QoS. Simulation results validate that the proposed scheme can achieve high efficiency and improve packet delay performance.
