application programming interface A northbound interface is an application programming interface (API) or protocol that allows a lower-level network component to communicate with a higher-level or more central component, while -- conversely -- a southbound interface allows a higher-level component to send commands to lower-level network components. The purpose of northbound API Northbound APIs are the link between the applications and the SDN controller. The applications can tell the network what they need (data, storage, bandwidth, and so on) and the network can deliver those resources, or communicate what it has
