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.

Abstract: Various embodiments of a method and apparatus for controlling transaction flow in a communications fabric is disclosed. In one embodiment, an IC includes a communications fabric connecting multiple agents to one another. Each agent may include an interface coupling itself to at least one other agent. Each interface may include multiple queues for storing information corresponding to pending transactions. Also included in each interface is an arbitration unit and control logic. The control logic may determine which transactions are presented to the arbitration unit for arbitration. In one embodiment, the control logic may inhibit certain transactions from being presented to the arbitration unit so that other higher priority transactions may advance. In another embodiment, the control logic may reduce the priority level of some transactions for arbitration purposes to prevent the blocking of other higher priority transactions.
