Software defined networking architecture standardization

The Software Defined Networking (SDN) architecture was developed in the Open Networking Foundation (ONF) Architecture working group. It is intended to support standardization related to the broader area of software defined networking and affects not only the understanding and related work within ONF, but across a number of standards and/or open-source development organizations. This article provides a brief outline of the SDN architecture, its relation to Network Function Virtualization (NFV) and areas for further study.
