    摘要: In one embodiment, a method that receives at a cache server device a request from a client device for a first representation of a content chunk; determines whether the first representation is available at the cache server device; responsive to determining that the first representation is available at the cache server device, provides the first representation to the client device; responsive to determining that the first representation is unavailable at the cache server device, determines whether a congestion-like condition is present in an upstream network; and responsive to determining that the congestion-like condition is present in the upstream network, provides a second representation of the content chunk.

    摘要: A method is provided in one example embodiment and includes communicating content to a content receiver, where a first portion of the content has a first drop priority. The method also includes determining a buffer status for a buffer at the content receiver, and adjusting the first drop priority to a second drop priority for a second portion of the content based on the buffer status. In more particular embodiments, the second drop priority can be higher than the first drop priority of the first portion of the content if the buffer is full or above a threshold. Also, the second drop priority can be lower than the first drop priority of the first portion of the content if content in the buffer has not started to render.
