OpenFlow Legal Information

The OpenFlow Switch Consortium publishes a specification of the OpenFlow Switch and the OpenFlow Protocol – it essentially provides a means for a flow table inside a switch to be controlled remotely. While the specification doesn’t describe the controller, it is expected to be an open development environment, such as a PC running Linux. The OpenFlow Switch specification is available under a BSD-like license, and will be free for implementation by anyone. Switch vendors who implement the base requirements of the OpenFlow Switch Specification Version 1.0 will be free to describe their switch as “Conforming to the OpenFlow Switch Specification (Version 1.0)”, so long as the switch supports the OpenFlow Protocol. Switch vendors will be free to implement additional features over and above those specified by the Consortium, and may wish to limit use of OpenFlow to “educational and government use only”. OpenFlow is a trademark of Stanford University, and with the written permission of Stanford, may be used to describe switches that conform to the OpenFlow Protocol.
