摘　　要：文中报告了中国电信网运营成本概况,主要分析了EPON系统中的节能效果。在EPON系统中,ONU能够在没有数据传输时切换他们的发射机,使其关闭——这种低功耗模式,被称为半休眠模式。说明了半休眠模式和动态带宽分配(DBA)算法对EPON系统的节能影响,对基于使用了3种不同DBA算法的两种半休眠模式"laggy"和"swift"的节能潜力进行了分析和比较,特别是这两种半休眠模式对能源效率和帧延迟的不同影响的评估。This paper gives the operating costs of China Telecom network and analyzes the energy-saving effect in EPON system. In EPON system, ONU can switch its transmitters into temporary shut when there is no data transmission and this low power consumption mode is known as doze mode. This paper also explains the effect caused by doze mode and dynamic bandwidth allocation （DBA） algorithm on EPON system, then analyzes and compares the energy-saving potential of two doze modes ＂laggy＂ and ＂swift＂ based on three different DBA algorithms, in particular the evaluations on different effects of energy efficiency and average frame delay caused by these two doze modes.

关 键 词：半休眠模式 能源效率 平均帧延迟 动态带宽分配
