About 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 DUTs in the lab. All rates from 10GE to 100GE are supported by a single 2-slot test module.

Chimera is ideal for NEMs who want to optimize Quality of Experience (QoE) for customers by ensuring their equipment can handle acceptable levels of impairment. Service providers, enterprises, and government agencies can also use Chimera to validate Quality of Service (QoS) for voice, video, and data traffic being sent across their networks.

Chimera can be used a “standalone” solution, but it can also be installed as a test module in a ValkyrieBay chassis for seamless integration with ValkyrieManager’s traffic generator. This provides a really simple way of emulating impairment to traffic being generated via Valkyrie all from the same GUI.

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

Benchmarking
Stress testing/ Negative testing
“What-if” testing
Regression testing

Chimera can function as a standalone traffic impairment emulator. Or it can be installed in a Valkyrie chassis to seamlessly add impairment to traffic (up to 100GE) being generated by the other Valkyrie test modules.

CHIMERA IN VALKYRIEMANAGER

When a Chimera test module is installed in a ValkyrieBay chassis, ValkyrieManager detects its presence and makes the Chimera’s software options available for adding impairment. This makes it very easy for test engineers to emulate impairment via the same GUI they use for generating the stateless Ethernet traffic.

This diagram illustrates how the Chimera test module emulates impairment. Incoming traffic enters a flow filter and different types of impairment are then added (as defined in the UI), with each traffic flow being processed in a prioritized order.

Two hardware options

Both options below support impairment emulation at all rates from 10GE to 100GE via a single Chimera test module.

TEST MODULE (Chi-100G-5S-2P)

Chimera is currently available as a 2-slot test module for a ValkyrieBay chassis, the Val-C12-2400G, where ValkyrieManager is used to emulate impairment as part of it standard user-interface.

STANDALONE CHASSIS (C-Chi-100G-5S-2P):

ChimeraCompact is a standalone version of Chimera where the test module is installed in a quiet desktop-sized chassis.
