Experimenters in GENI have used OpenFlow controllers based on these frameworks (in alphabetical order): * [https://openflow.stanford.edu/display/Beacon/Home Beacon] Beacon is a java-based controller built by David Erickson at Stanford. For more information look at the Beacon's [https://openflow.stanford.edu/display/Beacon/Home wiki page]. * [http://floodlight.openflowhub.org/ FloodLight] * [https://code.google.com/p/maestro-platform/ Maestro] * [http://noxrepo.org/ NOX] * [http://trema.github.com/trema/ Trema] You can find a performance comparison for some of this controllers [http://www.openflow.org/wk/index.php/Controller_Performance_Comparisons here] If you're a GENI experimenter using an OpenFlow controller based on something else, drop a note to help@geni.net, and we can add a link here. We also plan to add more information about these controllers in the future.
