Frequently asked questions
To validate large-scale network infrastructures, it’s essential to emulate millions of network flows and routing paths seamlessly across physical chassis, virtual machines, and cloud platforms. This approach supports full line-rate throughput testing of Layer 2 and Layer 3 protocols, ensuring realistic simulation of complex topologies, VPNs, and software-defined networks (SDN). Using scalable emulation across diverse environments helps identify performance bottlenecks, protocol interoperability issues, and security vulnerabilities early, which accelerates development and deployment of robust, high-performance data center and AI fabrics.
Accurate emulation of AI data center traffic includes Layer 2–3 protocols, VPNs, broadband services, SDN control traffic, and RDMA over Converged Ethernet version 2 (RoCEv2). Including congestion control protocols and encrypted traffic like MACsec is vital to replicate real-world AI training and inference workloads. Testing these protocols under realistic network conditions helps ensure lossless data delivery, network security, and optimized throughput in AI fabrics, enabling robust validation of high-performance computing and hyperscale cloud infrastructure.
Tailored AI fabric testing focuses on critical aspects like secure and lossless Ethernet infrastructure, dynamic MACsec key rotation, and zero-packet-loss RDMA performance. Emulating AI training and inference workloads enables network engineers to validate the reliability and security of high-throughput data flows between GPUs, accelerators, and switches. This specialized testing reduces the risk of data loss or security breaches in AI clusters, ensuring consistent, low-latency communication required for large-scale AI and machine learning deployments.
Realistic traffic emulation replicates diverse, multi-service network conditions, including encrypted VPN traffic, broadband applications, and SDN signaling. This approach ensures tests reflect actual usage patterns and protocol interactions under varying load and congestion scenarios. Accurately modeling these traffic types enables identification of performance bottlenecks, latency issues, and packet loss, providing deeper insight into network behavior. Consequently, network engineers can optimize configurations and validate compliance with service-level agreements (SLAs) to ensure consistent user experience and high network availability.
