7 TYPES OF TESTS Valkyrie is typically used for these core test solutions
8 TYPES OF TESTS Performance Testing • Performance testing focuses the performance of a DUT via parameters Stream Oriented Traffic generation and reception • like maximum throughput, latency and jitter. Statistics tracked per stream, or user-defined packet header filters • Analysis of throughput, latency, jitter, loss, sequence, and misorder errors • Valkyrie provides comprehensive generation and analysis of Ethernet Generate 100’k unique traffic flows using Modifiers • traffic including analysis of throughput, latency, jitter, loss, sequence, and Generate stream based on import of PCAP files • misorder errors. Results can be presented in easy to understand tables, Real-time performance logging with charting and histograms • charts and histograms and documented in customizable reports. Reporting in PDF or HTML files • Polling of counters with logging to CSV or XML file • Wire-speed and event triggered packet capture and export to Wireshark W H I T E P A P E R S _____________________________________________________________________________________________________________________________________________________________ G . f a s t V S P E R F G P O N T e s t i n g 1 0 0 G P O N

10 TYPES OF TESTS Certification & Interoperability Being able to verify and document that devices and services meet international standards for performance and interoperability is an important test scenario. Xena participates regularly in interoperability testing events. Valkyrie is used for certification & interoperability testing: Valkyrie is used for certification testing of G.fast per IR-337 which provides a • G.fast per ID-337 set of functional, stability, and basic performance test cases and related • GPON per TR-247/ATP-247/TR-255 pass/fail requirements for G.fast implementations according to ITU-T Recommendations G.9700 and G.9701. For GPON devices, Valkyrie is used to perform the tests described in the Broadband Forum’s specification OD-247/IR-247.

11 TYPES OF TESTS Quality Assurance Testing • RFC2544 Quality Assurance (QA) gives companies a systematic way to maximum • Throughput analysis consistent product quality by minimizing errors and mistakes in products. QA • Lost packets statistics testing typically includes stress testing of environmental conditions, e.g. EMC • Latency analysis tests, mechanical drop and shock tests, heat and humidity tests. When testing Ethernet products Valkyrie is used to generate Ethernet traffic from outside a test chamber into the DUT to verify it performs as expected. Other features like timestamping of results and industry-leading automation options make Valkyrie ideal for QA testing.
