英文摘要:
The power communication network is an important carrier of the business in power system. The new power communication network incorporating SDN(Software defined network) can provide better information transmission for system services. SDN controller deployment has a significant impact on SDN network functionality. Based on the characteristics of the power communication network, a novel SDN controller deployment method for the power communication network is proposed in this paper. Node importance is imported in model. The reliability and delay problems are solved by a harmony search algorithm combined with non-dominated sorting. The simulation analysis is carried out on the IEEE30 communication node system. The method in this paper and CNPA (Clustering-based Network Partition Algorithm) was compared. The results shows that the method in this paper has better applicability to the power communication network.
