Abstract
In order to effectively solve the problem of time delay degradation caused by the sleep technology in the Optical Net-work Unit (ONU)of Time and Wavelength Division Multiplexed Passive Optical Network (TWDM-PON),a green dynamic bandwidth allocation algorithm based on traffic-aware is proposed.By combining energy saving mechanisms such as the receiv-ers and transmitters sleep independently and sending sleep control signaling one by one and mixed sleep,the sleep time of transceivers are extended as long as possible,so as to reduce the energy consumption of ONU.In addition,by sensing the traf-fic,the bandwidth demand of services in the short future can be predicted.Therefore,the polling cycle length are dynamically adjusted according to the bandwidth demand of delay sensitive services,so as to meet the requirement of service quality and minimize the delay of expedited forwarding service at the same time.Simulation results show that the proposed algorithm can effectively reduce the energy consumption at the ONU in TWDM-PON under the premise of ensuring the quality of service.关键词
