WaveQoE™ - End User Quality of Experience Test

WaveQoE™ - End User QoE Test - offers network developers, QA engineers, installers and IT staff the capability to accurately determine how well business applications will perform in different usage situations, such as education, retail, corporate office, hospital and carrier networks. Application performance metrics provide the means for determining whether the system measures up to desired quality levels. These metrics precisely quantify the results, define a Service Level Agreement (SLA) in terms of quality thresholds, and compare actual measured test results to the desired SLA’s.

WaveQoE is designed for testing of edge network devices such as access routers, gateways, security-enabled switches, application accelerators and WAN accelerators.

Using WaveQoE, it is easy to model real-world deployment scenarios and study the end-users’ actual quality-of-experience. Creating “what if” scenarios to effectively plan for changes or added services, makes this an ideal solution for network managers, service providers and network equipment vendors.

Benefits

• One system autonomous test solution for converged wired and wireless networks
• Ready to use traffic models representing virtually all LAN and WLAN network applications with their associated user mix and behavior characteristics.
• Create unique usage models to fit a particular network behavior
• Effectively ensure the performance of critical applications before rolling them out on the production network.
• Establish an application certification process for different wired and wireless network deployments
• Discover equipment design flaws affecting application performance early in the development cycle
• Reproduce intermittent performance problems in the lab to ease troubleshooting and improve service levels
• Identify and fix security holes in network deployments exposed by complex interaction of different client and application security schemes
• Dramatically reduce test and support costs, and increase test/debug/fix cycle efficiency thereby improving time-to-market

Test Description

WaveQoE accurately replicates the complex interaction of clients, servers and traffic profiles in wired and wireless LAN’s. By creating usage profiles and traffic mixtures that were found to be representative in various network environments, the test measures and reports key application layer metrics that affect end-user Quality of Experience (QoE).

The networks replicated include: health-care, education, airports, warehouses, retail, hot spots, and service provider managed services.

Test Results and Metrics

• The WaveQoE test provides both real-time results and final test results and metrics. These results can be exported in a comma separated value (.CSV) file format or HTML to facilitate results analysis and reporting.
• Automatically generated PDF test reports provide executive summaries, including comprehensive graphs, a description of the test, the significance of the results, and detailed results for drill-down analysis
• Results include metrics directly affecting the user experience, such as:
  • VoIP MOS scores, Video MDI scores, HTTP/FTP Goodput levels, FTP file transfer times, etc.
  • Over time results displayed in real-time
  • Total intended load, offered load and achieved load
  • Percentage of traffic flows of traffic types that satisfied the SLA
  • Percentage of clients of each client type that satisfied the SLA
