Keysight Showcases Link Layer Retry Interoperability with Alibaba Cloud at 2026 OCP Global Summit

Asad Khamisy, Senior Vice President and General Manager, Core Switching Group, Broadcom

“As AI systems scale to larger accelerator domains, Ethernet serves as the vital enabler for high-performance scale-up connectivity, delivering unrivaled bandwidth, resiliency, and efficiency. Demonstrating 1.6T Link Layer Retry interoperability with Tomahawk 6 showcases how the open Ethernet ecosystem is rapidly innovating to power these demanding AI workloads while maintaining a flexible, standards-based architecture. Collaboration with Keysight and Alibaba Cloud helps validate these technologies across the ecosystem and accelerate Ethernet adoption in next-generation AI infrastructure.”

Dennis Cai, VP of Engineering, Head of Network Infrastructure, Alibaba Cloud

“Large-scale AI infrastructure depends on networking technologies that combine high performance with reliability, interoperability and operational simplicity. Demonstrating LLR and CBFC on Alibaba Scale-Up Ethernet switch platform based on Broadcom Tomahawk Ultra provides an important validation in a hyperscale implementation. Working with Keysight and Broadcom helps advance an open Ethernet ecosystem where emerging scale-up technologies can be validated consistently across silicon, systems and real-world deployment environments.”

Ram Periakaruppan, Vice President and General Manager, Network Test & Security Solutions, Keysight

“AI scale-up networks require more than higher bandwidth — they require predictable, lossless and interoperable transport across an increasingly diverse ecosystem. By working with Broadcom and Alibaba Cloud to validate LLR and CBFC across multiple SerDes generations, switch architectures and 1.6T and 400GE interfaces, Keysight is helping the industry move Ultra Ethernet link-layer technologies from specification to deployable technology. Our goal is to provide the independent validation infrastructure that enables silicon, systems and cloud providers to adopt next-generation Ethernet scale-up and scale-out technologies with confidence.”
