Time waits for no man – especially if he wants to succeed in finance. The high pace of international trading means millisecond delays can impact bottom line results. Measuring the impact of latency and jitter on networks and services is essential for improving financial performance. That’s where Chimera comes in.
Customers increasingly expect the same experience when they are on the move as when they are at home. Service providers use Chimera to validate Quality of Service (QoS) for voice, video, and data traffic being sent across their networks.
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, 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.
New features in Chimera 3.0:
– Improved flow filtering
– Impairment statistics
– Flow impairments (CLI + UI)
– Jitter (Gaussian)
– Frame corruption (BER and FCS)
– Frame mis-ordering
– Frame duplication
– Packet Drop (Burst and Gilbert-Elliot)
– Bandwidth policing (ingress)
– Bandwidth shaping (egress)
– Latency (‘Accumulate & Burst’)
– Port impairment (UI + CLI)
– PMA error pulse injection
– Save / Load Chimera port impairment settings
– SyncE: All ports can sync to recovered clock from single Rx port (CLI only)
Known limitations
– Chimera impairments do not work with Micro TPLD (Valkyrie feature)
Up-coming Chimera releases will further refine the current feature set. More details will be provided soon. For the latest news, please contact us directly.
