Network management and control method and system, network system, and storage medium

A network management and control method, which is applied to a data acquisition apparatus communicatively connected to a network management and control system, the network management and control method comprising:

• generating Digital Twin (DT) model data corresponding to physical objects in a physical network;
• and
• sending the DT model data to the network management and control system, so that the network management and control system generates network configuration information according to the DT model data, and delivering the network configuration information to the physical network, so that the physical network implements network management and control according to the network configuration information, wherein the network configuration information is generated by the network management and control system according to a target analysis result, the target analysis result is obtained by the network management and control system according to a collaborative relationship and all DT cases at different levels, the DT cases at the different levels are generated by the network management and control system according to the DT model data, the levels of the DT cases correspond to levels of physical objects, and the DT cases at the different levels have a functionally collaborative relationship.
