Abstract
A method of managing bandwidth allocation across a video pipe that delivers both streaming adaptive bitrate (ABR) content and progressive download ABR content includes receiving a designation of a congestion boundary within a video pipe, the congestion boundary designating a first percentage of the video pipe that is to be used for streaming ABR content when congestion exists on both sides of the congestion boundary, wherein a remaining percentage of the video pipe is to be used for progressive download ABR; allocating bandwidth for streaming ABR content, wherein the gateway device can allocate for streaming content only that portion of the remaining percentage of bandwidth that is not requested for progressive download content; and allocating bandwidth for progressive download content, wherein the gateway device can allocate for progressive download content only that portion of the first percentage of bandwidth that is not requested for streaming content.
