Abstract: In an embodiment, a method comprises receiving a first data streamed from a first server computer at a first site; collecting a first throughput data for the first site based, at least in part, on a first throughput of the first data streamed from the first server computer; receiving a second data streamed from a second server computer at a second site; collecting a second throughput data for the second site based, at least in part, on a second throughput of the second data streamed from the second server computer; switching from the second server computer at the second site, to a third server computer at the first site, based, at least in part, on a comparison between the first throughput data and the second throughput data; wherein the method is performed by one or more special-purpose computing devices.

Abstract: One embodiment of the present invention sets forth a technique for adapting playback bit rate to available delivery bandwidth in a content delivery system comprising a content server and a content player. A content player periodically estimates whether a given playback bit rate can feasibly provide complete playback for a given title assuming currently available bandwidth. If playback becomes unfeasible at a current bit rate assuming currently available bandwidth, then the content player adapts the bit rate downward until a feasible bit rate is achieved. If playback is feasible using a higher bit rate, then the content player may adapt the bit rate upward.

Abstract: Techniques for optimizing a plurality of parallel network connections for a digital content stream through a network between a plurality of content servers and a content player. Embodiments determine an indication of network performance for each of the plurality of parallel network connections. Additionally, upon determining that a first one the plurality of parallel network connections is underperforming, based on whether the indication of network performance associated with the first parallel network connection satisfies a threshold level of performance, the first parallel network connection is dropped. Upon determining that a total throughput for the digital content stream is less than a minimum threshold of network performance, embodiments select a content server with which to establish a new parallel network connection, based on historical network performance data associated with the selected content server, and also establishing the new parallel network connection to the selected content server.

Abstract: Embodiments of the present invention set forth techniques for a content player to stream a media file using multiple network connections. To stream the media file, the content player downloads metadata associated with a requested media file, establishes a network connection with multiple content servers (or multiple network connections with a single content server or both) and begins requesting portions of the media file. In response, the requested portions are transmitted to the content player. The content player may employ a predictive multi-connection scheduling approach to determine which network connection to use in downloading a given chunk.
