SDN Definitions – Software Directions
•Northbound Interface
•In computer networking and computer architecture, a northbound interface of a
component is an interface that conceptualizes the lower level details
(e.g., data or functions) used by, or in, the component
• Examples: SMMP, CORBA, SNMP
•Southbound Interface
•Allows a particular network component to communicate with a lower-level
component
• Example: Openflow, Netconf, SNMP
•East-West Interface
•Communicate between groups or federations of controllers to synchronize state
for high availability
