Abstract
In some embodiments, a method receives one or more segments for content from a first content delivery network during a playback session for the content. The content includes a number of segments. The method evaluates buffer occupancy of a buffer configured to store segments of the content for playback and evaluates a number of times of a failure to download a segment for the content. The buffer occupancy is compared to a first threshold and the number of times of the failure to a second threshold. The method determines a switch from the first content delivery network to a second content delivery network during the playback session based on the comparing.
