The twins can interact with the real physical network in real time, restore the operating state and environment of the real physical network through modeling and mapping, perform pre-verification before network deployment, and thus provide the optimal network strategy solution, improving the reliability of network decision-making and deployment.

It helps standardize research in the digital twin network design phase and is very meaningful for the implementation of digital twin network construction technology.

[0061] In another embodiment provided by the present invention, the implementation process of step S1 includes the following steps:

[0078] In another embodiment provided by the present invention, the verification pass conditions include that the network delay is lower than a preset delay threshold and / or meets the preset network performance requirements.

[0079] That is, when the network delay is lower than the preset delay threshold, it indicates that the control strategy verification is passed;

[0080] Or, when the digital twin environment is running and meets the preset network performance requirements, it indicates that the control strategy verification is passed;
