Abstract: In general, this disclosure describes techniques of dynamically selecting versions of media content based on data transfer policies of a media content provider that provides the media content. As described herein, a media content provider may establish a variety of data transfer policies for a variety of purposes. When requests are received, versions of media assets indicated by the requests are selected such that an overall bandwidth utilization of the media content provider is likely to be substantially equal to a desired bandwidth utilization established by one or more of the enterprise data transfer policies.

Abstract: A parallel download system is described to download data from a plurality of source servers in parallel. The system may include a source scheduler, a prioritization scheduler, and an I/O dispatcher. The source scheduler generates a download schedule to control which source servers will be downloaded from at a current point in time. The prioritization scheduler tracks the latency and throughput of all channels to the source servers and dynamically adjusts the download schedule to control download performance. The I/O dispatcher produces an output stream to present the downloaded data to one or more external applications or a user.
