What is the purpose of a southbound API in a control based networking architecture?

  • A. Facilities communication between the controller and the applications
  • B. Facilities communication between the controller and the networking hardware
  • C. allows application developers to interact with the network
  • D. integrates a controller with other automation and orchestration tools.

Correct Answer: B
Explanation: The Southbound Interface

In a controller-based network architecture, the controller needs to communicate to the networking devices. In most network drawings and architecture drawings, those network devices typically sit below the controller, as shown in Figure 16-5. There is an interface between the controller and those devices, and given its location at the bottom part of drawings, the interface came to be known as the southbound interface, or SBI, as labeled in Figure 16-5.
