Which group of APIs are used by an SDN controller to communicate with various applications?

  • westbound APIs
  • northbound APIs
  • southbound APIs
  • eastbound APIs
Explanation & Hint:

In the context of Software-Defined Networking (SDN), the group of APIs used by an SDN controller to communicate with various applications is referred to as northbound APIs.

  • Northbound APIs are used for communication between the SDN controller and the higher-level applications and business logic. These APIs allow the network to be programmed and managed by these applications, facilitating automation, orchestration, and network programmability.
  • Southbound APIs, on the other hand, are used for communication between the SDN controller and the network devices (like switches and routers). A common example of a southbound API is OpenFlow.
  • Westbound APIs and eastbound APIs are not standard terms in the context of SDN architecture.
