What is SDN?
Enabling Intelligent Orchestration
Software-defined networking (SDN) is a network framework that addresses a CSP's need for speed, adaptability, and automation – all of which are crucial for staying competitive in today's communications marketplace. SDN involves separating a network's control functions from its data forwarding functions, centralizing its intelligence, and abstracting its underlying architecture from applications and services. Fully-integrated control software gives CSPs the ability to operate and adjust SDNs from a centralized software utility, enabling intelligent orchestration.

SDN was developed by researchers and data center architects who were seeking a new way to control network devices without the need to update the software on each device every time a new protocol was created. By making their network devices programmable and configurable from a central element, these researchers gained a huge level of control over their networks and the ability to automate network behaviors quickly.
