Design and Application of a Network Planning System Based on Digital Twin Network

As a real-time representation of physical entities in the digital world, digital twin (DT) has been widely used in several industrial fields, bringing significant efficiency gains and cost reductions. Network planning is a very important stage in network life cycle management. At this stage, comprehensive and effective use of network data and historical experience can not only greatly reduce the cost of network planning and construction, but also speed up the production and launch of technologies and products. In this paper, a network planning system based on digital twin network (DTN) is proposed. Aiming at the key problems faced by current network planning, we complete the overall architecture design of the system and the detailed design of each unit. Finally, we verified the applications of this system in practice, including the closed-loop process of network planning, the entire life cycle management of data, and the visualization of the whole process of network planning. It is shown that by using this general digital system, the efficiency and accuracy of network planning can be effectively improved and the cost can be reduced.
