ICA-XFG-203 is 2-unit advanced, instructor-led course module that offers detailed exploration of the Tofino Native Architecture (TNA) facilities that are used to implement multi-path traffic distribution mechanisms such as Link Aggregation Groups (LAG), Equal-Cost Multi-Path (ECMP), Weighted-Cost  Multi-Path (WCMP) and similar. 

This course is recommended to all data and control plane designers tasked with implementing LAG, ECMP, WCMP, Load Balancing and other similar features in their systems as well as to anyone interested  in learning TNA in depth.

ICA-XFG-203 is a part of Intel® Connectivity Academy XFG course series and can be taken either in-person or online.

Starting 26th February – 27th February – is a 2-unit course about action profiles, selectors and traffic distribution.


Upon the completion of the course, the students will:
1. Understand the concept of action indirection and how it can be efficiently implemented using the ActionProfile() TNA extern.
2. Understand the principles of hash calculation, including Hash() and CRCPolynomial() externs.
3. Understand the algorithm of action selection employed by the ActionSelector() extern.
4. Understand the resilient hashing implementation.
5. Understand how to implement stateful hashing, such as spraying and flowlet hashing.
6. Learn how to write P416/TNA programs that perform traffic distribution.
7. Learn how to control the abovementioned TNA externs using Barefoot Runtime Interface


Each unit consists of a 2-hour-long lecture (presentation) with one break and is followed by the hands-on labs.


This course is most suitable for data plane designers tasked with implementing P4 programs on Intel Tofino™ ASIC family devices.


To attend an online presentation, you will need to create a free Zoom account, associated with your work email address. Upon the registration, you will receive a link to the online event. You will also receive invitations to establish accounts on Slack and the P4ica Support Portal for lab support and materials access, also associated with your work email address.


As your trusted partner for all things P4 and Intel Tofino, STORDIS is thrilled to guide you on this transformative journey. Don’t miss this opportunity to dive into the future of networking and become a specialist in P4 development.
