As a network engineer in a software-defined networking (SDN) environment, you are developing an application that needs to exchange information with the SDN controller to retrieve network performance data. Which type of interface should your application use to communicate with the SDN controller?
Your application should use the Northbound API to communicate with the SDN controller. Northbound APIs allow external applications to interact with the controller for tasks like network management and data retrieval. The Southbound API is used by the controller to communicate with the underlying network devices. The Data Plane interface is concerned with forwarding data packets, and the Management Plane interface handles network management but not necessarily the application-to-controller communication in SDN.
