Identify the southbound interfaces. 6) Data plane is also called _____. To perform these tasks, every controller uses a southbound interface such as OpenFlow. Notice the “Northbound” APIs (protocols) communicate between your network management station running its network apps and the SDN controller. In a figurative sense, northbound flow can be thought of as going upward, while southbound flow can be thought of as going downward. This is not a physical interface but a software interface, often an API (Application Programming Interface).… Control layer lies in middle and it exposes two types of interfaces – Northbound and Southbound. The raw data needs to be interpreted and there might be special rules related to collecting historical data and sending commands. The main objective of a southbound interface is to provide communication and management between the network's SDN controller, nodes, physical/virtual switches and routers. Classes and modules In summary if you are implementing a new protocol in ONOS the protocol module should only contain: API sub-module with interfaces describing operations and state logic CTL sub-module with implementation of the logic for the exposed interfaces Dependencies on third party libraries that enable communication to and from the device. The “Southbound” APIs occur between the controller and the actual network devices themselves. ChinaCom 2018. Recently, the SDN/OpenFlow discussions have started to talk about Northbound and Southbound API interfaces to the SDN controllers.
