【摘要】 针对EPON用于智能电网用电信息采集系统,提出了一种专用于该系统的SG-DBA算法。该算法根据电网用电信息采集特点,为电网重要事件提供最小带宽保证,并根据数据存储量按比例分配剩余带宽。仿真结果表明,该算法在保证电网重要事件及时上传的同时,提高了带宽利用率,减少了信息采集总时间。更多还原

【Abstract】 A new dynamic bandwidth allocation(DBA)algorithm of ethernet passive optical network(EPON)is proposed in smart grid electricity information collection system. The algorithm ensures minimum bandwidth for important events, and allots the remaining bandwidth according to the storage proportion based on the characteristics of smart grid electricity information collection. It is showed by simulation that the algorithm can ensure the important events timely uploaded with higher bandwidth utilization and less collection time.更多还原
