You do the math.
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.
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.
Both options below support impairment emulation at all rates from 10GE to 100GE via a single Chimera test module.
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.
ChimeraCompact is a standalone version of Chimera where the test module is installed in a quiet desktop-sized chassis.
A step-by-step guide to how Chimera works using Xena’s live demo system. You can try this yourself right now.
This Chimera video covers:
1. Downloading & installing the Chimera software
2. Connecting to Xena’s live demo system
3. Configuring the Chimera & Loki test modules,
4. Creating traffic streams and mapping the streams to flows, and
5. Adding impairments to the individual flows.

How to add some basic types of latency and jitter to Ethernet traffic using Chimera.
This video shows you how to add:
– Constant latency
– Step function
– Uniform jitter
– Gaussian jitter

How to control bandwidth using Chimera.
Shows you how to use Chimera to limit the bandwidth of Ethernet packet flows passing through a device, using the policers and shapers of the impairment pipeline.

How to filter flows using Chimera.
Shows how Chimera flow filters are used to map incoming packets to up to 8 different flows per port. Each flow can then be independently impaired.

New features
Release 4 includes support for these new impairment distributions:
We’ve also made it easier to create highly customized impairment distributions with just a few mouse-clicks:
Extended timing mode: Increased “Reduced Bandwidth” max. latency = 10 sec. (CLI only)
Frame corruption:
Added support for selecting L1 / L2 policing and shaping.
