This tutorial is suitable for both P4 newcomers and existing practitioners. You should have basic knowledge in computer networking, some programming skills, and basic knowledge of UNIX-based operating system.
Information will be sent by email to registered participants, appear on the conference platform (Whova) as well as posted here.
The tutorial requires participants to bring and use their own laptop.
It is recommended (but not mandatory) to have a Raspberry Pi platform ready for the tutorial. Please refer to our Required Equipment page.
If you don't have a Raspberry Pi platform, you can use instead P4App. The instructions are here.
We strongly recommend preparing a microSD card with the latest P4Pi image prior to the hackathon, as downloading the image and copying it can take significant time.
To do so, follow the instructions on the Installing P4Pi page.
If after the tutorial you would like to learn more about P4 and P4Pi, the following resources can be useful.
If you are new to P4, we strongly recommend the P4 Learn page.
The following four short videos by Stephen Ibanez are also recommended:
- Part 1 - Introduction to Data Plane Programming
- Part 2 - Basics Part I
