SCENARIO
As more content is offered in high definition (HD) and service providers charge a premium for it, subscribers are likely to churn faster when dissatisfied. Degradation in audio/visual QoE leads today’s consumer to competitor solutions that offer a better end-user experience. With traffic levels high and expected to grow for the foreseeable future, service providers are challenged to assess video quality with realworld traffic loads in pre-deployment testing.
Customers need to be able to:
• Measure the ability of a transport network to carry video data.
• Determine the optimal user session limits of edge and origin media servers, content proxies, etc.
• Stress-test middleware devices, such as encoder systems and DRM.
• Measure the perceived quality of the video delivered to the end user.
• Determine the total number of streams a CDN can handle.
• Test the performance of key IPTV infrastructure service
IXIA SOLUTIONS
Ixia provides a comprehensive test solution for video delivery platforms with IxLoad. IxLoad delivers the industry’s most scalable and flexible solution for realistic load testing of over the top (OTT), VoD, IPTV media, and cache platforms to validate end-to-end video delivery architectures. Emulate thousands of interactive on-demand and live streaming user sessions and measure real-time video quality.
This Ixia solution enables customers to:
• Emulate adaptive streaming behavior that dynamically up shifts or down shifts the media stream to deterministically play back streams of different quality.
• Create static profiles of user behavior that are fixed on different playback levels to deterministically play back streams of different quality with no network heuristic at play.
• Define subscribers’ activities and flexible channel viewing sequence with scenario editor.
• Validate video streaming delivery systems and interoperability with real video sharing services by exercising OTT video protocols over TCP and QUIC.
• Support data, voice, and video protocols simultaneously to emulate a multiplay subscriber environment with an intelligent, real-time issue isolation mechanism.
