Research on IP and Optical Layer Cooperative Control in Power Communication Network

Abstract

With the rapid development and popularization of the energy Internet, the demand for power services has proliferated, and existing power communication networks cannot provide efficient dynamic network services that match them. Software Definition Network (SDN) proposes a new system and idea to solve the current network problems. At present, IP and optical network have different network architecture, switching technology and control and management mechanism, which makes it difficult to cooperate between IP layer and optical layer, thus making the network scalability poor, transmission efficiency and resource utilization low, and it is difficult to meet the needs of the current power communication network. In view of this, this paper studies the SDN-based IP and optical layer cooperative control architecture, establishes the IP and optical layer fusion network perception model, and proposes the SDN-based IP and optical layer cooperative operation and maintenance control scheme, which provides a theoretical basis and demonstration reference for the construction of a new generation of power communication network with unified control of resources, coordinated network and data scheduling, and rapid response to business needs.
