Explanation
Southbound APIs are used to communicate between the SDN controller and the switches and routers within the infrastructure. OpenFlow and Cisco OpFlex provide southbound API capabilities. OpenFlow is the standard southbound protocol used between the SDN controller and the switch. The SDN controller takes the information from the applications and converts them into flow entries, which are fed to the switch via OF. It can also be used for monitoring switch and port statistics in network
