This repostitory contains the implementation for the OPP software switch and controller.

Our goal is to devise a data plane abstraction and prototype implementations for future-proof network devices capable to be repurposed with middlebox-type functions well beyond static packet forwarding, with a focus on stateful processing and packet generation.

The repository is organized as follows:

• opp/switch contains the implementation of the user-space software switch;
• opp/ctrl contains the implementation of the controller compatible to the software switch;
• Use cases, applications and examples exploiting the OPP functionalities can be found in the opp/ctrl/ryu/app/beba/ folder.
