Design of Routing Strategy for SDN-based Power Communication Network

In power communication network, load balancing can reduce the overload of bottleneck nodes, and help to improve the reliability of power communicatio network and the utilization of network resources. As the main trend of the next generation power communication network, the research on survivability strategy has always been a hot topic. Aiming at the unique structure and flow characteristics of power communication networks, this paper proposes a load balancing routing protocol based on conditional constraints. Among them, the algorithm based on resource optimization dynamically adjusts the weight of the link by comparing the difference between the load of links and the overall average value of the network during the routing process, so as to ensure the overall load balance of the network. The simulation results show that, compared to the traditional algorithm, its dynamic weight setting plays a certain optimization role in reducing the variance of network load. While satisfying different constraints, it can still maintain a high resource utilization rate, which meets the different needs of the business in the future development of power communication network.
