Due to a ransomware attack, the wiki was reverted to a July 2022 version. . We apologize for the lack of a more recent valid backup.
The goal of this tutorial is to teach you the basics of P4, P4Runtime, and ONOS. It includes also is targetted to beginners who have little or no knowledge of the P4 language and would like to learn more using ONOS as the control plane. It includes hands-on exercises that you can run on a tutorial VM. In the exercises, you where you will learn how to create an emulated network of P4 devices using Mininet and BMv2 (the reference P4 software switch) controlled by ONOS via P4Runtime, while using a custom simple P4 program implementing a custom tunneling protocol named "MyTunnel".
