Why Network Emulator 3?

In this video, meet Keysight Network Emulator 3 — the fastest interface speed network emulator supporting 100GE, 25GE, and 10GE Ethernet impairment platforms. Built with application-aware emulation engines, it delivers precise control over network impairments such as latency, jitter, and packet loss, allowing you to test application performance under real-world network conditions with unmatched accuracy. Watch how it helps you uncover hidden performance issues, debug application behavior, reduce deployment risks, accelerate release cycles, and ensure consistent user experiences before connectivity disruptions ever reach your users.

Network Emulator 3: 100GE, 50GE, 40GE, 25GE, and 10GE Impairment

Effective testing requires a real-world environment that reproduces realistic network conditions and behavior. All software and hardware should be subjected to a realistic test environment before deployment.

Network Emulators Catalog

This catalog highlights Keysight’s Network Emulator 2 and Network Emulator 3 solutions, enabling precise replication of real‑world network impairments across 100 MbE to 100GE Ethernet. It provides performance details, use cases, architecture capabilities, and supporting tools for validating application robustness, interoperability, and network resilience before deployment.

Why Impairment?
