Keysight Technologies introduced the APS-ONE-400, a modular 4x100GE network application and cybersecurity test platform designed to generate high-scale Layer 4-7 traffic, encrypted TLS traffic, security attacks, Zero Trust Network Access (ZTNA) scenarios, and Elephant Flows associated with AI and large language model workloads. The 1RU appliance targets network equipment manufacturers, service providers, and data center operators that need to validate network performance and security under increasingly complex traffic conditions.
The APS-ONE-400 delivers 400 Gbps of Layer 4-7 throughput, 380 Gbps of hardware-accelerated encrypted TLS throughput, and 95 Gbps of Elephant Flow throughput. The platform supports 100GE, 25GE, and 10GE interfaces through fanout configurations and can operate as a standalone appliance or integrate with Keysight’s existing APS-100/400GE systems, including the APS-M8400, APS-M1010, and APS-ONE-100.
Keysight designed the platform for modular expansion into hyperscale test environments. When combined with the APS-M8400 appliance or APS-M1010 management controller, APS-ONE-400 systems can generate up to 16 Tbps of Layer 4-7 traffic, 15 Tbps of TLS traffic, 20 billion concurrent connections, and 25 million TLS connections per second. The platform also supports post-quantum cryptography-encrypted TLS traffic, allowing network and security vendors to evaluate infrastructure against emerging cryptographic workloads.

“The exponential growth of data transfers and bandwidth demands generated by AI and machine learning workloads is putting unprecedented strain on data center, service provider, and enterprise network infrastructures. Continuously validating that networks can handle these challenges without compromising security requires realistic, hyperscale, traffic emulation capabilities. Keysight’s modular APS-ONE-400 compute node delivers new heights in realism, emulating the traffic flows associated with generative AI models and agentic applications at hyperscale, including the huge Elephant Flow datasets common to LLM training use cases and PQC-encrypted traffic flows, all in a compact form factor that conserves critical lab resources,” said Ram Periakaruppan, Vice President and General Manager of Keysight’s Network Test and Security Solutions.
🌐 Analysis: The APS-ONE-400 reflects the convergence of network performance testing and cybersecurity validation as AI clusters introduce larger flows, higher interface speeds, encrypted traffic, and more demanding connection-scale requirements. The ability to combine application traffic, Elephant Flows, TLS workloads, PQC-encrypted traffic, and security testing on a modular platform gives Keysight a way to address network validation across AI data centers, service provider infrastructure, and equipment development labs without requiring separate test systems.
