P4 Tutorial

Introduction

Welcome to the P4 Tutorial!

We've prepared a set of exercises to help you get started with P4 programming, organized into four modules:

Introduction and Language Basics

P4 Runtime and the Control Plane

P4 Runtime

Monitoring and Debugging

Advanced Data Structures

Dynamic Behavior

Load Balancing

Obtaining required software

If you are starting this tutorial at the Fall 2017 P4 Developer Day, then we've already provided you with a virtual machine that has all of the required software installed.

Otherwise, to complete the exercises, you will need to either build a virtual machine or install several dependencies.

To build the virtual machine:

Install Vagrant and VirtualBox
cd vm
vagrant up
Log in with username p4 and password p4 and issue the command sudo shutdown -r now
When the machine reboots, you should have a graphical desktop machine with the required software pre-installed.

To install dependencies by hand, please reference the vm installation scripts. They contain the dependencies, versions, and installation procedure. You can run them directly on an Ubuntu 16.04 machine:

sudo ./root-bootstrap.sh
sudo ./user-bootstrap.sh
