Explore an open source implementation of the Ultra Ethernet Consortium's Ultra Ethernet Transport (UET) protocol built on the XDP2 programming model in this 40-minute conference talk. Learn about XDP2's "write once, run anywhere, run well" philosophy, which enables developers to create high-performance, programmable data plane applications in their preferred language that can be optimized for various hardware and software targets. Discover how UET, a modern transport protocol specifically designed for AI/ML scale-out networking, addresses the complex performance requirements of artificial intelligence and machine learning workloads that demand hardware-speed execution. Examine the implementation of UET's two foundational layers - the Packet Delivery sub-layer and Semantic sub-layer - through live demonstrations and detailed source code analysis. Gain insights into the mapping strategies for hardware implementation to achieve maximum performance, and understand why XDP2 serves as an ideal platform for deploying sophisticated networking protocols like UET in demanding computational environments.
