Simple. Scalable. Open.
Software-Defined Networking (SDN) solves existing network problems to enable highly complex social systems and increasingly intricate systems built with information and communications technology (ICT) to be constructed more simply and flexibly.
Software-defined networking (SDN) has demonstrated the capacity to turn the network into an enabler of modern IT environments and business needs and not a bottleneck.
The concept of SDN is to externalize the control plane to a centralized controller or other service. By centralizing the controller or service, opening APIs, and using software to program the network, SDN can help to eliminate the manual processes, configuration inflexibility, and latency challenges associated with device-centric networking.
