This section may need to be rewritten entirely to comply with Wikipedia’s quality standards, as it seems to deviate from the SDN development history as described in this source. This section’s factual accuracy is disputed. Relevant discussion may be found on Talk:Software-defined networking. The history of SDN principles can be traced back to the separation of the control and data plane first used in the public switched telephone network as a way to simplify provisioning and management well before this architecture began to be used in data networks.

These early attempts failed to gain traction for two reasons. 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. Ethane project at Stanford’s computer sciences department. That same year witnessed the creation of NOX—an operating system for networks. Beyond academia, the first deployments were by Nicira in 2010 to control OVS from Onix, co-developed with NTT and Google. A notable deployment was Google’s B4 deployment in 2012. SDN architectures decouple network control and forwarding functions, enabling network control to become directly programmable and the underlying infrastructure to be abstracted from applications and network services.
