摘要： Techniques are described for adjusting parameter settings for bitrate selection algorithms for devices streaming media content. Control parameter settings are selected for playback of first media content. Test parameter settings are selected for playback of second media content. If the test parameter settings result in better playback performance relative to the control parameter settings, the test parameter settings become the new control parameter settings.

摘要： Techniques for delivering live streaming content are described by which a streaming heuristic is selected based on the delay between the live and client playheads. For live content for which the delay is short, a low latency streaming heuristic is selected which is designed to handle live content streams for which only a few seconds of content can be buffered. For live content for which the delay is longer, a higher latency streaming heuristic is selected which is designed to handle streams for which the delay is sufficient to build a buffer of content fragments.

摘要： Techniques are described for adjusting parameter settings for bitrate selection algorithms for different segments of a population of devices streaming content. Streaming sessions are identified according to session characteristics. Within each segment of sessions, control parameter settings are sent to devices corresponding to a subset of each segment. Test parameter settings are sent to devices corresponding to another subset of each segment. If the test parameter settings result in better playback performance relative to the control parameter settings, the test parameter settings become the new control parameter settings, and new test parameter settings are generated.

摘要： Techniques are described for balancing traffic among content delivery networks (CDNs). A CDN balancer can analyze CDN performance data and determine CDN balancing ratios used to distribute traffic among the CDNs.

摘要： Techniques are described for switching streaming of media content between content delivery networks (CDNs) during mid-stream. An initial CDN can be used to stream the media content. The performance of a second CDN can be measured by requesting a fragment of the media content as a measurement or test fragment. Streaming of the media content can be switched to the second CDN if its performance is determined to be better than the initial CDN.
