Some Basic Definitions

What Is Software Defined Network (SDN)?

"...In the SDN architecture, the control and data planes are decoupled, network intelligence and state are logically centralized, and the underlying network infrastructure is abstracted from the applications..."

Note: SDN is not mandatory for network programmability nor automation

Source:

What is OpenStack?

Opensource software for building public and private Clouds; includes Compute (Nova), Networking (Quantum) and Storage (Swift) services. Note: Applicable to SDN and non-SDN networks

What Is OpenFlow?

Open protocol that specifies interactions between de-coupled control and data planes

Note: OF is not mandatory for SDN Note: North-bound Controller APIs are vendor-specific

What is Overlay Network?

Overlay network is created on existing network infrastructure (physical and/or virtual) using a network protocol. Examples of overlay network protocol are: GRE, VPLS, OTV, LISP and VXLAN

Note: Applicable to SDN and non-SDN networks
