Today’s Internet is a product of over forty years development, beginning with the ARPANET in the late 1960s and the formulation of the TCP/IP protocol in the early 1970s. We are now poised for the next major change in Internet development with the introduction of Software Defined Networking (SDN) – network architecture (hardware and software) that allows creation of “virtual internets” using potentially new protocols, running over the fiber optics and other hardware of today’s Internet. The National Science Foundation began funding university research in SDN under the GENI Project Office and moved to large scale prototyping in 2009. The Open Networking Foundation has been formed by all the big players in networking technology to further develop open standards (OpenFlow) and help brings these opportunities to the mainstream. All your next routers are going to be speaking OpenFlow in 2014!
