What is software defined networking (SDN)?

December 5, 2019 by Jack prabha  

Software Defined Networking (SDN) has become one of the most popular ways for organizations to deploy applications. This technology has been instrumental in allowing organizations to deploy applications at a faster rate, and reduce the overall cost of deployment. SDN gives administrators the ability to manage and provision network services from a centralized location. The benefits of this setup are such that more organizations than ever before are starting to ask ‘what is SDN’ and making the transition.

SDN stands for Software Defined Networking. SDN is an approach to networking that uses open protocols like OpenFlow to control software at the edge of the network. It is used to control access to switches and routers. It is nearly impossible to find a collective definition of SDN as its architecture can vary considerably from one organization to the next.

However, the basic purpose of SDN is to allow users to virtualize their hardware. A software-defined network attempts to build a computer network by separating it into two segments. The control plane can provide performance and fault management of NetFlow, IPFIX and SNMP protocols. This plane is generally used to manage configurations of devices connected to the SDN on a remote basis.
