Alan Weckel, Founder and Technology Analyst at 650 Group, discusses the deep transformation underway in data center networking.
As GPU and XPU deployments accelerate, network bandwidth requirements are increasing by 10x to 100x compared to traditional architectures. Weckel describes rapid evolution and the technologies driving it — from 1.6 Tbps deployments and emerging 448 Gbps solutions to new approaches that move beyond the classic InfiniBand vs. Ethernet debate.
He discusses how scale-up architectures are reshaping the foundations of AI infrastructure and offers insights into the engineering breakthroughs that will define the next generation of petabit-scale networks.
