SDN is an acronym of Software defined network and is defined as a systematic process that aims to provide an approach through which a network is intelligently and centrally controlled and programmed. This networking approach is very advantageous for the network operators to effectively manage the overall network. SDN enables programming of network behaviour in a centralised manner. All network platforms implementing a common SDN framework.
SDN is the abbreviated form of Software Defined Networking. It is an approach in which software applications can centrally control the network performance. Network can be programmed with the help of SDN and network can be controlled centrally through software applications. The main purpose of SDN is to focus on services that run on the network instead of putting hardware together in the form of network. SND consist of five components- control plane, north-bound application protocols, East-west protocols, data plane, open flow.
Software defined networking (SDN) is a type of architecture, which aims to make more flexible and agile. The primary aim of the SDN is to increase signal data transmission and to improve network control by allowing services providers and enterprises to respond quickly to changing business requirements. A network administrator or engineer can maintain the traffic from a centralised console without any physical intervention within the network. The centralized SDN controller carried out the switches to deliver services of network wherever they are required of the certain connections among devices and server.
