Over the past few years, continuous innovation and the need to adapt to the constraints of conventional networking has made software defined networking (SDN) pretty popular. Let's discuss what is so special about SDN that legacy technology is not able to deliver.
The current design of network infrastructure does not support dynamic scalability, central control and management, end-to-end visibility and dynamic traffic load distribution. It is an approach that physically separates the network's control plane from the data plane. This allows network administrators to program directly without having to worry about the commodity hardware specifications.
The following diagram shows SDN architecture. The SDN architecture can be divided into three layers: Application Layer, Control Plane, and Forwarding Plane.
In this section, we will...
