You are writing a Python application that will send instructions to an SDN controller, and you need to decide how to format those instructions. Which of the following data formatting types is commonly used to send instructions from an application to an SDN controller?

HTTP

Incorrect

Although Hypertext Transfer Protocol $($HTTP$)$ verbs $($e$.$g$.$ GET and POST$)$ are used to send instructions, the instructions themselves don't use HTTP formatting.

OpenFlow

Incorrect

OpenFlow is sometimes used as a Southbound Interface $($SBI$)$ to communicate between an SDN controller and a network device $($e$.$g$.$ a router or switch$).$ However, Openflow is not a type of data formatting.
