Initially this was a library built from the lessons learned in the ONF submission. Some of the code from the submission was moved directly, while other bits were rewritten. While the ONF submission was built from the OpenFlow message layer up, the Freeflow stack is being built starting with the system interface layer. Since then the Freeflow project has evolved into Flowgrammables a highly programmable and re-configurable protocol agnostic data plane. This project is approached from both sides of the application stack. From the top level we are developing a high level configuration language which produces application modules. At the lower level we are also developing a highly configurable protocol agnostic data plane run time system that is defined and executed in accordance to the application modules. Any questions or comments regarding freeflow can be addressed on our development mailing list.
