摘　　要：提出了一种基于Qo S的电力光纤到户网络规划方法。首先,结合不同建筑物的配电结构进行具有针对性的光网络单元(optical network unit,ODN)线路路径设计;然后,以通信成本为优化目标,以接入容量、可靠性、时延等为约束条件,建立最优化问题模型,并采用智能算法进行求解;最后,核算所规划网络的光路衰减,以满足实际应用需求。仿真结果表明,提出的基于Qo S的电力光纤到户网络规划方法可以在保证业务可靠性、时延要求的前提下,节约网络建设成本。A QoS-based network planning method for power fiber to the home was proposed.Firstly,the distribution structure of different buildings was combined to carry out targeted ODN line path design.Secondly,in the ONU packet cluster planning stage,in order to meet the QoS requirements of multi-service differentiation,the communication cost as the optimization goal was uesd,and the optimization problem model was established with the constraints of access capacity,reliability and delay.At the same time,intelligent algorithms were used to solve the optimization problem model.Finally,the optical path attenuation of the planned network was calculated to meet the actual application needs.The simulation results show that the proposed QoS-based network planning method for power fiber to the home can save network construction cost while ensuring service reliability and delay requirements.
