Hello friend！
What is a northbound interface?
The northbound interface (NBI) is an interface for vendors or carriers to access and manage networks, that is, the interface provided by the. The network uses interface programming to develop various applications to manage the managed objects. The management method is to collect and analyze the data generated during the running of the managed objects. In telecommunication networks and NGN networks (next-generation convergent networks), management is implemented hierarchically. The network management can be divided into three layers: application layer, data processing layer, and data management layer. Interfaces are defined for data interaction between the application layer and the data processing layer. Because the application layer is located above the data processing layer, such interfaces are called northbound interfaces.
Type of the northbound interface
NBIs are usually called Intf.N. They are classified into three types: CORBA, SNMP, and Syslog. The three types of NBIs perform different functions in network access and management.
1. The Syslog encapsulates alarms generated by the SNMP agent (a network management process that uses the SNMP protocol) into the format defined by the Syslog interface and sends them to the data processing layer.
2. The CORBA and SNMP interfaces support many functions, such as querying data and status of faults, topology, and resources, and delivering control and configuration data.
Hope this helps!
