Overview
Initial CDN Selection provides a wide range of parameters and rules on which to base the selection of CDN in a multi-CDN environment.
The parameters offer highly granular and detailed means to make sure that the selection of the delivering CDN is made with an optimized viewing quality for the end customer in mind.
The Initial CDN Selection service can be used for all your video service traffic or for your selected part of the traffic.
With parameters ranging from simple percentage-split between CDN A, B or C, to time of day and more advanced selection criteria such as client’s geographic location, ISP connection or the content type (live vs VoD) the active choice of CDN offers a valuable opportunity to make sure your streaming video services are delivered from the most optimal CDN
A detailed set of rules for different session groups can be created within the service. These can then be applied in a hierarchical structure, adjusted and weighted against your choice of different parameters. For example, a rule could be implemented to split the traffic equally between two CDNs, but in one particular region it could be refined to better suit those specific conditions.
The Execution of the rules can be followed in the service’s dashboard GUI, and the associated impact on quality tracked and studied. Useful insights can then be gained into how viewing quality is impacted by the change of CDN selection parameters and rule settings.
