XENA Chimera - Ethernet Impairment Emulation up to 100Gbps

Why choose Chimera?

Chimera is a network impairment emulator that makes it easy to introduce consistent, accurate, well-defined and repeatable impairments (e.g. packet manipulation, latency, jitter, bandwidth control and shaping) to traffic between test objects in the lab. All rates from 10GE to 100GE are supported by a single 2-slot test module.

Chimera is ideal for network device manufacturers who want to optimize Quality of Experience (QoE) for their customers by ensuring that their devices can handle acceptable degradations. Service providers, enterprises and government agencies can also use Chimera to validate Quality of Service (QoS) for voice, video and data traffic transmitted over their networks.

Chimera can be used as a stand-alone solution, but can also be built into a ValkyrieBay chassis as a test module to allow seamless integration with the ValkyrieManager traffic generator. This provides a really easy way to mimic traffic degradation generated by Valkyrie using the same GUI.

Finally, Chimera is available at a price/point that is approximately half the industry standard.

Key Applications

Chimera makes it easy to emulate network impairment, making it an extremely cost-effective and convenient solution for:

  • Benchmarking
  • Stress tests / negative tests
  • “What-if tests?
  • Regression tests

Valkyrie Manager

ValkyrieManager is the Windows-based application that allows Ethernet data streams to be configured and generated between Xena’s Valkyrie testers and Devices Under Test (DUTs) at speeds of up to 400 Gbps to analyze results.

When ValkyrieManager detects a Chimera test module in a Valkyrie chassis, Chimera’s software options for adding impairments are available in ValkyrieManager, allowing test engineers to manage the emulation of impairments through the same GUI they use to generate traffic.

Chimera Manager

ChimeraManager is a web-based interface for configuring and emulating consistent, accurate, well-defined, and repeatable degradations such as latency and jitter in traffic between test items in the lab.


Chimera can be used as a stand-alone unit or integrated into a Valkyrie chassis.

ChimeraCompact is a 19″ rack-mountable housing that can also be used as a desktop device without any problems.

In a ValkyrieBay chassis, a Chimera test module requires 2 of the 12 slots.


Chimera can emulate impairment at these five Ethernet speeds:


Chimera is Xena’s new Ethernet impairment emulator. It’s fully integrated with our Valkyrie Ethernet traffic generator, making it the only hardware-based solution on the market that lets you use the same GUI to both generate and impair wirespeed Ethernet traffic, right up to 100Gbps. This makes it easy to use and highly cost-effective.
