Checking out OpenFlow

To get the most current development version of OpenFlow, use GIT and issue the following command:

git clone git://openflowswitch.org/openflow

This will check out the experimental branch of our repository to your local directory.

Adding OpenFlow to a Switch, Router or Access Point

Either download the current release version of OpenFlow or follow the instructions above to get the current development version. Both contain a kernel space and user space implementation, for a switch you will most likely want the user space implementation. Both implementations are licensed under the OpenFlow License which in most cases allows you to add it to your switch or router’s code base.

Stanford also maintains an implementation on OpenFlow on Broadcom switching chipsets. If you are developing for a Broadcom based platform please contact us and we in most cases can provide you with the source code.

Developing an OpenFlow Controller

If you want to develop an OpenFlow controller, you can have a look at the controller that is part of the OpenFlow test suite. A more full-fledged OpenFlow controller is NOX. It is available under the GPL at NOX Repo.

Bugs and Support

Please report and feature requests for the reference implementation or the test suite via Trac.

If you need support with a specific issue or have other questions please post to the openflow-discuss mailing list.
