NBI North Bound Interface

A northbound interface (NBI) is the interface to a component of higher level layer. A NBI is an output-oriented interface that is usually found in networks and network elements. An example of a NBI implementation is a device that only sends SYSLOG messages and cannot be manipulated to take any kind of input. The lower layer's NBI links to the higher layer's southbound interface (SBI).
