Research on Centralized Control Architecture Deployment of Power Optical Network Based on Network Perception

The current smart distribution new business is flexible and complex, and business needs are dynamic. The SDN-based power elastic optical network (SD-EON) combines the advantages of software-defined networks in network management and control and the advantages of flexible optical network spectrum resource utilization, which can meet the load-bearing requirements of smart distribution network services. The key to reliable bearer and information transmission of the distribution service is the survivability and efficient control mechanism of the power elastic optical network. Therefore, this paper designs an elastic optical network perception model for smart distribution network, and obtains network traffic and topology information through OpenFlow-based network state awareness method. Based on this, a centralized control deployment scheme for elastic optical networks for multi-media heterogeneous coordination of power grids is designed to realize intelligent centralized control of power elastic optical networks.
