What is SDN (Software Defined
Networking)?• According to Open Networking Foundation [ Purist definition ]
SDN is a new approach to networking in which network
control is decoupled from the data forwarding function
and is directly programmable.
The result is an extremely dynamic, manageable, cost-
effective, and adaptable architecture that gives
administrators unprecedented programmability,
automation, and control.
