VIAVI TestCenter L2-3 Testing Solution

VIAVI TestCenter is a comprehensive, end‑to‑end network, cloud, and AI‑data‑center validation platform designed to meet the performance, scalability, and reliability demands of next‑generation infrastructures. As a unified Layer 2–3 testing solution, TestCenter enables service providers, network equipment manufacturers, enterprises, and hyperscale data center operators to emulate real‑world conditions and verify network behavior across traditional, virtualized, and cloud‑native environments. It delivers high‑capacity traffic generation, deterministic measurements, extensive protocol emulation, and automated workflows to accelerate design, development, deployment, and troubleshooting. Engineered for the rapidly evolving landscape of high‑speed Ethernet, TestCenter supports interfaces ranging from 1G to 1.6T across a variety of hardware modules and appliances, offering extreme flexibility, scalability, and cost efficiency. The platform provides industry‑leading port density, multi‑rate operation, and broad support for optical and copper form factors, empowering users to validate throughput, latency, link training, FEC behavior, and end‑to‑end service quality under realistic, high‑stress conditions. Its modular architecture allows adaptation to growing test requirements, safeguarding long‑term ROI and ensuring compatibility with emerging network technologies. TestCenter is also optimized to address the rising complexity of AI infrastructure and AI fabric validation, where lossless Ethernet, extremely low latency, and high‑volume east‑west traffic patterns dominate. The platform emulates compute‑intensive AI/ML workload behavior, including Collective Communication Library (CCL) patterns running over RoCEv2 transport, enabling precise measurement of KPIs such as congestion response, flow control effectiveness (PFC/DCQCN), jitter, microbursts, retransmissions, and fabric stability under load. This allows operators to validate whether network fabrics can sustain GPU‑to‑GPU communication at scale without deploying large and costly xPU server farms. Complementing these capabilities, the next‑generation TestCenter D2 1.6T Appliance expands the platform’s AI‑focused capabilities by providing multi‑vendor testing environments, massive traffic generation capacity, and interoperability validation for 1.6T‑class Ethernet fabrics. It is designed specifically for the needs of hyperscalers and cloud providers building high‑density AI clusters, offering the ability to replicate real‑world AI workloads, validate fabric robustness, and ensure readiness for emerging optical and interconnect technologies. Across lab, pre‑production, and live data center scenarios, VIAVI TestCenter delivers actionable analytics, automation‑driven efficiency, and deep visibility—equipping organizations to confidently validate performance, reduce risk, accelerate deployments, and optimize next‑generation networks built for AI, cloud, and high‑speed Ethernet evolution. #VIAVI #TestCenter #NetworkTesting https://www.viavisolutions.com/en-us/products/testcenter
