3. What is SDN?

4. SDN Definition
“An approach to building computer networking
equipment and software that separates and abstracts
elements of these systems. These elements called as
control and data plane”.
~ English Wikipedia, 2013 ~
“A new approach to networking in which network control
is decoupled from the data forwarding function and is
directly programmable”.
~ Open Networking Foundation (ONF), 2013 ~
“An approach to networking in which control is
decoupled from hardware and given to a software
application called a controller.”

Entire network appears as aEntire network appears as a
single logical switch withoutsingle logical switch without
understanding the protocolunderstanding the protocol
processprocess
The control and data planes are decoupled, network
intelligence and state are logically centralized, and the
underlying network infrastructure is abstracted from the
applications
Programmability, automation, and network control, enabling
them to build highly scalable, flexible networks that readily
adapt to changing business needs
