Sep 7, 2022 · The basic principle of SDN is “to automate network supply, management and control through centralised policy/control engines based on software, that control network enabling endpoints”.
Software-defined networking (SDN) is a software-controlled approach to networking architecture driven by application programming interfaces (APIs). SDN leverages a centralized platform to communicate with IT infrastructure and direct network traffic.

An SDN controller platform typically contains a collection of “pluggable” modules that can perform different network tasks. Some of the basic tasks including inventorying what devices are within the network and the capabilities of each, gathering network statistics, and other monitoring functions, etc. Extensions can be inserted that enhance the fu...
The first SDN controller wasNOX, which was initially developed by Nicira Networks, alongside OpenFlow. In 2008, Nicira Networks (acquired by VMware) donated NOX to the SDN community, making it open source. It has since become the basis for many SDN controller solutions. Nicira then went on to co-develop ONIX with NTT and Google; ONIX is the base fo...
Software-defined wide area network (SD-WAN)has seen increased popularity among enterprises. One of the reasons for its popularity is that the centralized application-based policy controller leverages existing hybrid WAN architectures. The controller in conjunction with analytics brings network and application visibility.
SDN controllers are the software used to control a software-defined network (SDN).The controller software communicates with applications with northbound APIs.The controller software communicates with the network infrastructure with southbound APIs.SDN controller platforms are software modules that can be assembled to perform all of the tasks a controller must do.SDN Controllers (aka SDN Controller Platforms) in a software-defined network (SDN) is the “brains” of the network.

A controller, the core element of an SDN architecture, that enables centralized management and control, automation, and policy enforcement across physical and virtual network environments.
Software-defined networking (SDN) offers a centralised, programmable network that consists of an SDN controller, southbound APIs, and northbound APIs. SDN controllers are the brains of the network, offering a centralised view of the overall network.
