摘　　要：为提高电力通信接入系统的QoS能力,提出基于SDN技术的电力通信接入系统网络架构设计方法。首先,采用SND技术通过电力数据转发层、电力控制层和电力业务应用层设计电力通信接入系统的网络架构;其次,结合三角模算子和链路带宽占用率预测结果设计路由策略;最后,考虑网络流量传输速率和链路带宽利用率调度网络中的流量,来提高服务质量,完成设计。结果表明,阻塞率和资源占用率分别在10%和40%以下,负载均衡熵在0.8附近,丢包率在0.4%以下,端到端最长时延为0.034 s,说明其设计的电力通信接入系统网络架构具有良好的路由选择能力和队列调度能力。In order to improve the QoS capability of power communication access system,a design method of power communication access system network architecture based on SDN technology is proposed.First,SND technology is used to design the network architec-ture of power communication access system through power data forwarding layer,power control layer and power business appli-cation layer.Secondly,the routing strategy is designed by combining the triangular modulus operator and the link bandwidth occu-pancy prediction results.Finally,it considers the network traffic transmission rate and link bandwidth utilization to schedule the traffic in the network to improve the quality of service and complete the design.The results show that the blocking rate and re-source occupancy rate are below 10%and 40%respectively,the load balance entropy is around 0.8,the packet loss rate is below 0.4%,and the maximum end-to-end delay is 0.034 s,indicating that the designed network architecture of the power communica-tion access system has good routing and queue scheduling capabilities.
