At OCP 2026, Ram Periakaruppan, VP and GM, Network Applications and Security at Keysight Technologies, examines one of the most pressing problems in the AI buildout: how to validate AI infrastructure at scale. He walks through the three domains that define modern AI networking (scale-up, scale-out, and scale-across) and outlines the distinct technical hurdles each one presents, from the physical layer up through transport protocols.

Periakaruppan explains why the industry’s mix of high-speed interconnects, emerging open-standard protocols, and evolving optics is creating new validation challenges for hyperscalers and equipment vendors. He also identifies a fundamental shift in how AI infrastructure must be tested, and what it means for anyone qualifying components destined for large GPU clusters.
