摘要
针对以太无源光网络(EPON),为各类业务提供服务质量支持,特别是保障时延敏感型业务的服务质量,提出一种调度算法,应用到EPON的光网络单元(ONU)中。我们设法让这个单级调度算法具备多级调度功能。通过理论分析和仿真测试,证明本算法具有灵活的优先级机制和公平调度功能。
In order to support quality of service for different types of packet traffic, especially to guarantee quality of service of the delay sensitive traffic in Ethernet Passive Optical Networks （EPONs）, a scheduling algorithm was proposed, which was applied in Optical Network Units （ONUs） of an EPON. We tried to enable this single level scheduling algorithm with the functions of the hierarchical scheduling. With theoretical analysis and simulation test, the proposed algorithm is proved to possess the flexible priority mechanism and fair scheduling ability.
