Keysight Technologies has unveiled the APS-ONE-400, a modular 4x100GE network cybersecurity test platform designed to help network equipment manufacturers (NEMs), service providers and data center operators validate increasingly complex network environments. The compact 1-rack-unit (1RU) platform delivers high-performance Layer 4-7 traffic generation, encrypted traffic validation and Elephant Flow traffic testing while reducing infrastructure requirements. The launch comes as enterprises grapple with rapidly growing AI and machine learning workloads driving increases in network traffic, encryption demands and cybersecurity challenges. The APS-ONE-400 expands Keysight's APS-100/400GE hardware family, delivering up to 400 Gbps of Layer 4-7 throughput, 380 Gbps of hardware-accelerated encrypted TLS throughput and 95 Gbps of Elephant Flow traffic generation. When combined with the APS-M8400 appliance or APS-M1010 management controller, the platform can scale to generate up to 16 Tbps of Layer 4-7 traffic, 20 billion concurrent connections, 15 Tbps of encrypted TLS traffic and 25 million TLS connections per second.
