Abstract: This paper proposes a dual-route configuration method for power communication network based on safety degree. Firstly, by analyzing the needs of the power communication network, comprehensively considering the reliability, link balance and service transmission delay, the concept of safety degree is defined, and the safest path for the business is configured as the optimization goal. Then, based on the traditional Bhandri algorithm, combined with the actual power communication network, a safety degree based maximum disjoint dual-route configuration method is proposed. Finally, the effectiveness of the configuration method is verified through simulation experiments. The simulation results show that, compared with the traditional RF algorithm, the proposed configuration method can improve the balance of link resources in the entire network on the basis of configuring the maximum disjoint dual routes.
