BEBA Software Switch

This is an implementation of the BEBA Software Switch based on the CPqD OpenFlow 1.3 softswitch.

BEBA is a European H2020 project on SDN data plane programmability. 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.

A controller for this switch can be found at https://github.com/beba-eu/beba-ctrl

Features in a nutshell

The BEBA Switch is an OpenFlow 1.3 switch extended with support for:

• Stateful packet forwarding based on the OpenState API
• Packet generation based on the InSP API

Moreover, BEBA targets software accelleration. We improve the CPqD softswitch troughput while retaining the simplicity of the original CPqD code base.

Getting Started

Similarly to the CPqD softswitch, the following components are available in this package:

• ofdatapath: the switch implementation
• ofprotocol: secure channel for connecting the switch to the controller
• oflib: a library for converting to/from 1.3 wire format
• dpctl: a tool for configuring the switch from the console

For more information on how to use these components please refer to the original CPqD's documentation

Building

Run the following commands in the beba-switch directory to build and install everything:

$ ./boot.sh
$ ./configure
$ make
$ sudo make install

Running

Please refer to the original CPqD's softswitch README
