What is SDN?
© F5 Networks, Inc. 12
Definition of SDN:
“SDN is a family of architectures (not technologies) for operationalising networks with improved time to market, reduced risks, and reduced operating expenses by centralising control into a control plane that programmatically controls and extends all network data path elements and services via open APIs.”

SDN transforms IT by addressing factors that cause higher costs for, slows down deployment of, and result in customer dissatisfaction with applications
