This separation of control-plane/. data-plane provides a common protocol to program the forwarding plane and the ability to. easily program the network using applications on top of the controller. A SDN network defines three layers: the application layer, the control layer, and the. network layer. The applications use an application programming interface (API) to the. controller that has a connection to each switch, providing the ability to populate the flow.

Each flake nucleates around a dust particle in supersaturated air masses by attracting supercooled cloud water droplets, which freeze and accrete in crystal form. Complex shapes emerge as the flake moves through differing temperature and humidity zones in the atmosphere, such that individual snowflakes differ in detail from one another,
