【摘要】：为有效解决时分波分复用无源光网络(time and wavelength division multiplexed passive optical network,TWDM-PON)中因采用节能算法而导致的业务时延恶化问题,提出一种考虑业务QoS的光线路终端(optical line terminal,OLT)节能算法。通过建立针对局端设备光线路终端的新型能耗模型,使发射机和接收机能够独立地关闭或开启,从而在上下行业务不对称的情况下能够最大化地降低光线路终端能耗;通过区分业务、调整轮询周期的大小以及工作收发机的数目,保证不同业务QoS的要求。仿真表明,算法在保证业务QoS的前提下,最大化地降低了TWDM-PON中OLT的能耗。
[Abstract]:In order to solve the problem of time and wavelength division multiplexed passive optical network TWDM-PON, which is caused by the adoption of energy-saving algorithm, the problem of service delay deterioration in time-division wavelength division multiplexing (TWDM) passive optical network is effectively solved. This paper presents an energy saving algorithm for optical line terminal optical line terminus considering QoS. By establishing a new energy consumption model for the optical line terminal of local equipment, the transmitter and receiver can be turned off or turned on independently. Thus, the energy consumption of optical line terminal can be maximized under the condition of asymmetry of uplink and downlink services, and the requirements of QoS for different services can be ensured by adjusting the size of polling period and the number of transceivers through distinguishing service, and by adjusting the size of polling period and the number of transceivers. The algorithm maximizes the energy consumption of OLT in TWDM-PON on the premise of guaranteeing service QoS.
