Powering All Ethernet AI Networking

Artificial Intelligence (AI), powered by accelerated processing units (XPUs) like GPUs and TPUs, is transforming industries. The network interconnecting these processors is crucial for efficient and successful AI deployments. AI workloads, involving intensive training and rapid inferencing, require very high bandwidth interconnects with low and consistent latency, and the highest reliability to maximize XPU utilization and reduce AI job completion time (JCT). A best-of-breed network with AI-specific optimizations is critical for delivering AI applications, with any JCT slowdown leading to revenue loss. Typical workloads have fewer, very high-bandwidth, low-entropy flows that run for extended periods, exchanging large messages synchronously, necessitating advanced lossless forwarding and specialized operational tools. They differ from cloud networking traffic as summarized below:
