In April 2013 Nuage Networks announced their virtualized services platform software which included: a directory service for policy and analytics, an OpenFlow capable network controller, and a virtual and physical network forwarding plane.
In April 2012, Google's Urs Hölzle described how the company's internal network had been completely re-designed over the previous two years to run under OpenFlow with substantial efficiency improvement.
In 2012, Hölzle introduced "the G-Scale Network" on which Google had begun managing its petabyte-scale internal data flow via OpenFlow, an open source software system jointly devised by scientists at Stanford and the UC Berkeley and promoted by the Open Networking Foundation.
