Domestic communication network management is mainly divided into three types of network management: manufacturer's professional network management, professional integrated network management and inter-professional integrated network management. As the source of basic data, the manufacturer's professional network management provides data for the professional integrated pipe network and inter-professional integrated network management through the northbound interface of the network management.

Among them, the northbound interface is an interface defined for users to access and manage the network. Users must use the northbound interface to define and develop network management applications in the application layer, so that users can access and manage the network through these applications. The application is presented to the operator in the form of a simple, easy-to-use and intuitive interface. The operator sends commands through the interface click or configuration, while the northbound interface is used inside the system to send these commands to the data processing layer. The northbound interface processing process running at all times resides in the data processing layer. After this process receives the command sent by the application layer, it forwards the control command to the next layer: the data management layer for continued execution. If the received message is a request message, the data from the data management layer is encapsulated in the format specified by the northbound interface and returned to the application layer.
