VIAVI Solutions debuts Ultra Ethernet Transport validation for AI data center networks

Viavi launches validation solution for AI data center networks By Investing.com

CHANDLER, Ariz. - VIAVI Solutions Inc. (NASDAQ:VIAV) announced today the launch of a validation solution for Ultra Ethernet Transport in AI networks, according to a press release statement. The GPU-free offering for VIAVI TestCenter targets hyperscalers, cloud providers, and network equipment manufacturers. The solution validates AI back-end networks using the Ultra Ethernet Consortium's Ultra Ethernet Stack. The Ultra Ethernet Stack addresses AI and High-Performance Computing workloads. UEC 1.0 introduces a UET protocol for congestion control and scalability in Ethernet-based AI fabrics. VIAVI's solution emulates the transport layer of UET, replicating AI traffic patterns including reliable ordered and unordered delivery, packet trimming, congestion control and dynamic multipathing. The platform emulates AI workloads such as collective communications and large language model flows. It validates load-balancing mechanisms including ECMP, packet spraying and flowlet switching. "AI clusters will soon scale to millions of endpoints, which means relying on physical GPUs alone to validate network behavior is no longer practical," said Aniket Khosla, Vice President of Product Management, Optical Transport and High-Speed Ethernet at VIAVI. Mahesh Subramaniam, Senior Director of Product Management, AI Data Centers at HPE, stated the VIAVI TestCenter platform provides traffic emulation and visibility for validating congestion control and transport performance. HPE's collaboration with VIAVI includes UET transport validation using the Juniper QFX5240 platform and Junos Evolved. VIAVI Solutions provides test and measurement and optical technologies for data centers, communication networks, and other infrastructure sectors. The company, with a market capitalization of $12.97 billion, has seen remarkable momentum with shares surging 450% over the past year to $52.94, though InvestingPro analysis suggests the stock may be overvalued relative to its Fair Value. Revenue grew 30.6% in the last twelve months, and seven analysts have recently revised earnings upward, with the company expected to return to profitability this year.

In other recent news, Viavi Solutions Inc. announced its Xgig platform for PCI Express 6.0 specification testing received Gold Suite acceptance from PCI-SIG, enabling compliance testing at workshops globally. S&P Global Ratings upgraded Viavi Solutions to a BB rating from B+ after the company repaid its term loan B using proceeds from a $575 million common stock issuance. This upgrade reflects S&P's expectation of improved debt to EBITDA ratios in the coming fiscal years. Additionally, Viavi introduced a TETRA MS radio base station simulator option for its CX300 service monitor, enhancing its testing capabilities for TETRA MS radios. The company also partnered with Square Peg Communications to advance 5G non-terrestrial network technology testing. In a move to enhance network testing and validation, Viavi launched AI Experts, part of its NITRO AI portfolio, which includes automated tools for wireless testing. These developments highlight Viavi's ongoing efforts to strengthen its technological offerings and financial position. This article was generated with the support of AI and reviewed by an editor.

VIAVI Solutions Inc. Launches Ultra Ethernet Transport Validation Solution For AI Fabrics

VIAVI Solutions Inc. announced the launch of the industry's first Ultra Ethernet Transport validation solution for AI fabrics, bringing powerful traffic generation and analysis capabilities to hyperscalers, cloud and neocloud providers, as well as network equipment manufacturers across the broader Ultra Ethernet ecosystem. The new GPU-free, full-fidelity offering for VIAVI TestCenter is designed to accelerate the rollout of next-generation high-speed AI networks through the validation of scale-out and scale-up AI back-end networks using the Ultra Ethernet Consortium's Ultra Ethernet Stack. The Ultra Ethernet Stack is purpose-built for large-scale AI and High-Performance Computing workloads, with UEC 1.0 introducing a new UET protocol that delivers advanced congestion control and massive scalability to accelerate multi-vendor adoption of Ethernet as a primary transport for AI fabrics. VIAVI's UET validation solution enables customers to ensure that their AI fabrics deliver the required performance and resiliency without the cost and complexity of deploying dedicated GPU infrastructure. The solution emulates the transport layer of UET, replicating realistic, stateful AI traffic patterns at scale, including reliable ordered and unordered delivery (ROD/RUD), packet trimming, congestion control and dynamic multipathing. It also supports full-fidelity emulation of AI workloads, such as collective communications (CCL) and large language model (LLM) flows. In addition, the platform enables comprehensive validation of load-balancing mechanisms across the AI fabric, including ECMP, packet spraying and flowlet switching.
