Quality of Experience - NCM-WAN-Health-Dashboard/Quality-of-Experience

The Quality of Experience (QoE) feature provides a high-level, aggregated view of application experience for client traffic traversing an Ericsson endpoint. By sampling traffic flows and evaluating full end-to-end round-trip latency, either per interface or per application depending on endpoint class, QoE generates a simplified score of Excellent, Good, Fair, or Poor. This scoring enables quick visibility into the overall latency performance impacting client experience. Importantly, the QoE score reflects the cumulative impact of the entire traffic path and is not intended to isolate performance issues tied to any single network segment.

Click the Quality of Experience card to open the Quality of Experience page. The Quality of Experience page contains the Interfaces and Applications tabs. These tabs allow you to review QoE by router, router group, and by application.

The Interfaces tab contains a time-series graph of QoE for interfaces and a table of the interfaces. The table of interfaces lists each interface in the account and includes each interface's name, current status, type, and QoE and latency scores.

The Applications tab contains QoE information for the applications in use on your network. This application QoE information is displayed with a time-series graph that includes a bubble for each application. Hover over these bubbles to see bytes in/bytes out amounts for each application. Use the applications table on the Applications tab to see details (application name and bytes in/out for the network applications' QoE. Click an application name to view that application's QoE on a time-series graph.

The tables on both the Device and Applications tabs can be filtered by QoE scores by clicking the Filter button.

Latency is mapped to a logarithmic scale from 1 to 1000, where lower values indicate better QoE. The table below illustrates how latency ranges correspond to QoE scores.
