October 13th, Noon – 3:30pm (in-person) – San Jose Convention Center, Lower Level, Room LL21B
The P4 Workshop event is an opportunity for the P4 ecosystem to share knowledge, insights and experiences across the broader community and to facilitate collaboration. This year the workshop will be a hybrid event and feature both in-person and pre-recorded content. The in-person portion of the workshop will take place on October 13th in conjunction with the 2025 OCP Global Summit at the San Jose Convention Center in San Jose, California.
In addition, a P4 booth will be in the OCP Global Summit exhibit hall – make sure and stop by to talk with community members and learn about P4, how its used and how to participate. Don’t miss a demo – “Gigaflow: Pipeline-Aware Caching in Virtual Switches with P4”.

Assistant Professor Canada Research Chair in Minimizing Human Error in Modern Networks Cheriton School of Computer Science, University of Waterloo
Abstract: Over the past two decades, programming abstractios for packet processing have gained widespread adoption. These abstractions enable network operators to specify packet processing logic in high-level, domain-specific languages that are independent of the underlying hardware architecture of packet processing nodes. This approach has unlocked numerous benefits, including compiler-driven generation of efficient low-level implementations, portability across diverse execution environments, and automated testing and verification. Most existing abstractions, however, primarily focus on L2/L3 packet processing. In this talk, we highlight the need for new programming abstractions that capture the complexities of network mechanisms essential for quality of service, specifically transport protocols.

- KEYNOTE: Krishna Doddapaneni – “Using P4 NICs for resilient scale-out GPU interconnect”
Corporate Vice President, AMD Pensando
Abstract: AI transports demand hardware-based solution for low latency, high throughput GPU interconnects. P4 seems a perfect match for demanding datapath transport enabled on programmable NIC for scale-out Ethernet fabrics. The industry is standardizing packet processing, memory transfers, message processing, reliability, multipathing, etc. over the last few years. And we are at the beginning of building and standardizing these solutions. As network components multiplies — from cables and NICs to switches and transceivers, failures become an inevitability. Chasing a myth of perfect reliability, a more practical approach is to design a programmable network that anticipates and handles these failures gracefully.
This talk discusses how AMD leverages the P4 to build a robust solution that overcomes network failures, implementing a multi-plane architecture and advanced failure-handling mechanisms. How P4 capabilities demonstrate network data plane programmability is a foundational requirement in today’s demanding and unforgiving AI environments.
