摘要
摘要:传输时延和数据包丢失率是电力通信业务可靠传输重点关注的问题，该文提出一种面向软件定义电力通信网络的最小路径选择度路由控制策略。结合电力通信网络软件定义网络(SDN)集中控制架构的特点，利用图卷积神经网络构建的链路带宽占用率预测模型(LBOP-GCN)分析下一时刻路径带宽占用率。通过三角模算子(TMO)融合路径的传输时延、当前时刻的路径带宽占用率和下一时刻的路径带宽占用率，计算出从源节点到目的节点间不同传输路径的选择度(Q)，然后将Q值最小的路径作为SDN控制器下发的流表项。实验结果表明，该文所提出的路由控制策略能有效减小业务传输时延和数据包丢失率。

Abstract:Transmission delay and packet loss rate are critical issues in reliable transmission of power communication services. A minimum path selection routing control strategy for software-defined power communication networks is proposed. Combining the characteristics of the centralized control structure of the software-defined power communication network, a Link Bandwidth Occupancy Predictive model based on Graph Convolutional Network (LBOP-GCN) is built to analyze the route paths bandwidth occupancy in the next period. The selectivity (Q) of different transmission paths from the source node is calculated to the destination node is calculated by using Triangle Modular Operator (TMO) to fuse the transmission delay of the path, the path bandwidth occupancy at the current moment and the path bandwidth occupancy at the next moment. Then the path with the lowest Q value is used as the flow table of the OpenFlow switch delivered by the Software Defined Network (SDN) controller. Experiments show that the proposed routing control strategy can effectively reduce service transmission delay and packet loss rate.
