What is SDN?

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.”

~ SearchSDN, TechTarget, 2013 ~

Configure, manage, secure, Configure, manage, secure, and optimize network resources and optimize network resources

via dynamic and automated via dynamic and automated programsprograms

Entire network appears as a Entire network appears as a single logical switch without single logical switch without understanding the protocol understanding 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
