Abstract
A processing system may request, from an edge server, a first video chunk for a first segment and a second video chunk for a second segment of a video program stored in a cache of the edge server, where the first and second video chunks that are requested are encoded at a testing bitrate comprising a second lowest available bitrate in accordance with an adaptive bitrate streaming protocol. The processing system may further receive the first and second video chunks from the edge server via a network link, determine a bandwidth of the network link based upon the testing bitrate, the durations of the first and second video chunks, and an elapsed time to receive the first and second video chunks, and request a third video chunk for a third segment of the video program encoded at a highest available bitrate below the bandwidth of the network link.
