With programmable networks, you gain new methods to interact with services via controllers and application program interfaces. Network engineers benefit from SDN because they no longer have to wrangle individual network devices to offer network services, connect locations and applications, or govern resource and capacity utilization. The control plane is the brain of the operation, managing network services and deciding how and where packets should move throughout the network. In the current mainstream SDN architecture, the operating system and basic protocol functions on traditional hardware devices are retained, and the controller collects device information on the entire network, which has the following advantages: Network devices provide APIs so that development and management personnel can send instructions to network devices by using a programming language. Following this, no request is sent to the controller since all incoming flows will find a matching entry. One is that many in the Internet community viewed separating control from data to be risky, especially owing to the potential for a failure in the control plane. Initial SDN control plane proposals focused on a centralized solution, where a single control entity has a global view of the network.
