Welcome to Trema
Trema is a OpenFlow controller framework that includes everything needed to create OpenFlow controllers in Ruby and C.
This distribution includes all the source code of Trema you need to develop your own OpenFlow controllers. The source tree includes basic libraries and functional modules that work as an interface to OpenFlow switches.
Several sample applications developed on top of Trema are also provided, so you can run them as a sample of OpenFlow controllers. Additionally, a simple but powerful framework that emulates an OpenFlow-based network and end-hosts is provided for testing your own controllers. For debugging, a wireshark plug-in to diagnose internal data-flows among functional modules is provided.
