OVERVIEW
QoE-based Initial CDN Selection offers real-time QoE monitoring and CDN selection in one service. The real-time QoE metrics dictate which CDN the next session request should be directed to.
The service can measure the QoE for all – or parts of – the traffic using Edgeware’s AST capability and the concept of QoE agents. By using QoE agents you can select the sessions you want to measure, such as certain subscribers or content, clients within a particular location, randomly selected for a statistical representation or in combinations.
With the powerful AST capability, the data collected by the QoE agents coupled with artificial intelligence (AI), hotspots and intelligent alarms, the QoE-based Initial CDN Selection service will direct the next session request to the CDN offering the best suited level of performance, and optimize the viewer’s QoE.
The service offers deep insights into what is causing quality issues faced by the viewers. The QoE metrics can be grouped and categorized based on the level of severity, and by the actions
recommended to mitigate the quality issues.
For example, by using active A/B testing, all new sessions can be directed to another CDN to determine if such an action eliminates the quality issue or not. Using QoE monitoring for different
combinations of CDN and Internet Service Provider (ISP) can detect and mitigate quality problems due to ISP peering congestion. Allocating video sessions to an alternative CDN could
correct the experienced quality drop for the viewer.
