摘要：
Quality-of-service (QoS) support in Ethernet passive optical networks (EPON) is a crucial concern. However, most studies have only focused on optical line terminal (OLT) capacity allocation amongst multiple optical network units (ONU), and the further issue of intra-ONU allocation remains open. In this work a novel decentralized intra-ONU solution is presented using virtual-time schedulers. Results confirm good performance for a wide range of input traffic classes and loads.
