The Ultra Ethernet Consortium is creating a new networking standard designed specifically for the high demands of AI and high-performance computing (HPC) at a massive scale, aiming for up to 1 million nodes. This standard enhances traditional Ethernet by introducing innovative features like multi-pathing, flexible message ordering, and advanced congestion control to optimize bandwidth and reduce latency. Notable advancements include packet-level spraying for better multi-path efficiency, customizable delivery options, and receiver-based congestion management, along with ephemeral connections to lower state overhead. The goal is to ensure compatibility with existing systems while significantly boosting performance for AI and HPC applications.
