Abstract


The next generation Ethernet passive optical network (NG-EPON) is one of the most efficient transmission technologies for broadband access. However, the active component ONU in such network still consumes a lot of power especially in high-load traffic. Meanwhile, the high-load traffic could invoke many idle periods which could waste power in the network. This work aims to find those idle periods from current cycle and even on next cycle. The proposed scheme classifies ONUs into intra-sleep ONUs and inter-sleep ONUs and then transforms them to different range of temporal sleep modes for these ONUs to save power. Simulation results show that a satisfactory power saving effect is achieved in high-load traffic while keeping a low delay.
