Spirent Communications and Juniper Networks have successfully completed the first live public demonstration of ultra ethernet transport (UET), marking a major milestone for the evolving Ultra Ethernet Consortium (UEC) ecosystem. The demonstration took place at Interop25 Tokyo, where Spirent, Juniper, and Spirent’s long-standing partner in Japan, TOYO Corporation, jointly generated and forwarded UET traffic in a live network environment utilising the Spirent B3 800G Appliance and the Juniper QFX 5240-64OD Switch. The test topology also included RoCEv2 traffic, demonstrating seamless coexistence and interoperability, and earned the companies a coveted Interop ShowNet Special Prize. The Juniper switch with 800G interfaces successfully recognised and forwarded all traffic types, validating its readiness for UET-based deployments.
As hyperscalers continue to prioritise open, interoperable solutions for artificial intelligence (AI)/ machine learning (ML) back-end networks, the significance of the UEC initiative and its fresh approach to delivering AI and high-performance computing (HPC) performance is becoming ever more apparent. With the consortium approaching its first official specification release, Spirent and Juniper are playing a pivotal role in driving progress through rigorous real-world validation, helping to strengthen and refine the evolving ecosystem.
Commenting on the achievement, Praful Lalchandani, vice president (VP), products, data centre platforms and AI solutions, Juniper Networks, “We are honoured to have been recognised alongside Spirent with this prestigious award at Interop Tokyo. This award underscores the strength of our partnership and the innovation we are driving together in high-performance, AI-driven data centre networking. Juniper’s data centre solution, a cornerstone of Juniper’s AI-Native Networking Platform, continues to lead with operational simplicity, performance, and open architecture.”
He further added, “Validating performance and interoperability with emerging transport standards like UET is essential for ensuring next-generation infrastructure can meet the evolving demands of AI-driven networking.”
Meanwhile, Masatoshi Nishihara, general manager, Spirent Japan, said, “Dramatic growth in AI applications and workloads continues to create challenges for the industry, and this public demonstration illustrates our dedication to helping industry partners to meet these challenges. Spirent is committed to supporting emerging standards. By facilitating early adoption and validation of standards with comprehensive testing solutions, Spirent empowers organisations to confidently prepare for the transition to next-generation networking, while maintaining performance and reliability in increasingly demanding environments.”
