fox

Lightweight Openflow Controller, built on top of libevent.

Why?

Sure, there's nox/pox, Beacon, Maestro, but those can be either complicated, written in non-performant languages, or both.

What I really wanted was a simple tool that got out of my way and pushed the logic for the applications to the application. Writing an application, especially once you understand OpenFlow, should be fairly simple and straightforward. Fox does not provide all the complicated features provided by other OpenFlow controllers, but it does allow you to get up and running (hopefully performantly!) in a matter of hours.

Using fox

create an app that uses fox by:

  1. Creating a new a c file (app.c) that has an app_init function that takes a struct event_base *base and returns TK
  2. Initialize whatever event-driven stuff your app needs, create an openflow controller and register callbacks with it using controller_new and controller_register_cb.
  3. Add your app_init in the main function in fox.c

TODO: clean up this process: define app_init(base) in whatever apps/your_app.c make (your_app) && ./your_app
