The Data Domain Construction of Digital Twin Network

With the advantages of "high fidelity network verification, low cost network trial and error, whole life cycle management", the digital twin network has gained more and more attention and recognition in academia and industry. Data, mapping, model and interface, as the four key characteristics, are the basis for realizing the advantages of the digital twin network. Among them, data as the cornerstone of the digital twin network, its accuracy, integrity and authenticity are directly related to the model construction accuracy of the twin network. To meet the data requirements of the digital twin network construction, the data domain architecture is proposed, the capability requirements of each module of the data domain are defined, and the key technologies that each module may adopt are analyzed.
