OpenFlow Controllers in GENI

Experimenters in GENI have used OpenFlow controllers based on these frameworks (in alphabetical order):

Beacon is a Java-based controller that supports both event-based and threaded operation. Beacon was developed at Stanford.

FloodLight is a Java-based controller that was forked from the Beacon controller, and now is supported by a community of developers. FloodLight is released under the Apache License.

Maestro is a multi-threaded Java-based platform that allows developers to implement new OpenFlow controllers. Maestro was developed at Rice University.

NodeFlow is an OpenFlow controller written in pure JavaScript for Node.JS. Node.JS provides an asynchronous library over JavaScript for server side programming which is perfect for writing network based applications.

NOX is a C++ based platform that gives the ability to developers to implement new controllers by writing NOX modules in either C++ or Python. Writing new modules in Python is a very easy way to get started with a prototype controller. NOX was developed at Stanford University.

Trema is a C based platform that allows developers to write new controllers by writing Trema modules in either C or Ruby. Trema was developed by NEC.
