Rail-Optimized Networking for AI Training Workloads

Over the past decade, Clos-based leaf-spine architectures have become the default design for data center networking. They deliver predictable latency, horizontal scalability, and clean integration with BGP EVPN/VXLAN overlays. For most enterprise and cloud workloads, they re still the right architecture. But large-scale AI training, particularly distributed training of large language models, has…
