network performance

NVIDIA’s Spectrum-XGS Ethernet aims to link geographically dispersed AI data centers, addressing the capacity limitations of single-site facilities. This “scale-across” approach complements “scale-up” and “scale-out” strategies, using distance-adaptive algorithms and advanced congestion control to minimize latency and optimize network performance. Cloud provider CoreWeave will be an early adopter. The technology seeks to reshape AI data center planning, potentially reducing costs and improving performance by distributing workloads across multiple sites. Its success will depend on real-world effectiveness and navigating complexities beyond networking.
