Abstract: Content is received within a network at a content receiver and that is communicated from a content source, where the content comprises packets to be sent to the content receiver that are marked with a first drop priority or a second drop priority. A network priority is detected at the content receiver that is based at least in part upon a ratio of packets marked with the first drop priority to packets marked with the second drop priority within the content and also a determination at the content receiver of a rate of packets dropped that are marked with the first drop priority and a rate of packets dropped that are marked with the second drop priority.

Abstract: Content is received within a network by a content receiver based upon fetch requests by the content receiver to a content source, where the fetch requests for content are based upon a first adaptation logic scheme to fill a buffer of the content receiver at a selected rate and to download segments of content at selected encoding rates. A network priority is detected at the content receiver that includes an observed download rate at the content receiver that is greater than a fair share rate for other content receivers in the network. Fetch requests for content are revised in response to detection of the network priority, where the revised fetch requests are based upon a priority adaptation scheme that results in at least one of filling the buffer at a faster rate and downloading segments of content at higher encoding rates compared with the first adaptation logic scheme.
