Test complex topologies to accelerate data center validation

Keysight Fabric Emulator is a software-defined platform that emulates complex, multi-switch Ethernet-based data center topologies. It enables engineers to validate adjacent switches, network interface cards (NICs), data processing units (DPUs), and high-performance interconnects for network infrastructure during design, validation, and pre-deployment stages. It emulates realistic traffic patterns, congestion, and failure conditions to help chipmakers, hyperscale cloud providers, and system integrators reduce risk, accelerate development, and validate large-scale network performance in the lab. Select a model based on the number of concurrent hardware switches you need to achieve your desired scale, typically one or two. Request a quote for one of our popular configurations today.

Realistic topology emulation

Emulate entire two- or three-tier Clos network topologies with programmable oversubscription, Layer 2 switching, Layer 3 routing, and configurable port speeds.

Configurable data plane

Test realistic load balancing and routing using five-tuple or three-tuple hashing, with configurable quality-of-service and explicit congestion notification.

Impairment testing

Simulate congestion, packet drops, and background load up to 1 Tbps to observe system behavior under failure and stress conditions.

Scenario experimentation

Analyze network response to congestion and failures using controlled background traffic, packet loss simulation, and multi-tier chaos experiments.
