Abstract: The examples of the present disclosure provide a network management system, method, apparatus, and an electronic device. Wherein the network management system comprises a support unit, a data management unit, a business service unit and a display unit. The business service unit includes multiple groups of microservice subunits, each of the microservice subunits is used to provide a type of microservice, and the microservices provided by each group of the microservice subunits are jointly used to realize one management function. The support unit performs installation and deployment on all the microservice subunits through the same installation and deployment logic, and the support unit performs operation management on all the microservice subunits through the same operation management logic. The data management unit stores data of all the microservice subunits through the same data storage logic, and the data management unit encapsulates the access logic of each type of data into the same access logic.

Abstract: According to an example, a managing server may establish a relation that associates a downlink interface of a gateway device with information of configuration content, receive a request for configuration content from a network device, identify a downlink interface of a gateway device that is directly connected with the network device, and send configuration content corresponding to the downlink interface of the gateway device to the network device based on the relation that associates the downlink interface of the gateway device with the configuration content so as to implement configurations of the network device.
