Abstract
Systems, methods, and instrumentalities are disclosed for media caching proxy techniques (e.g., applications) that enable caching of multimedia content delivered, for example, using the Dynamic Adaptive Streaming over HTTP (DASH) protocol. A request may be received from a client for a media presentation description (MPD) file relating to media content. The media content may comprise a plurality of media segments. An MPD file may be received from cache. A subset of the plurality of media segments of the media content stored within the cache may be determined. An available bandwidth on a backhaul link may be determined. A dynamic MPD file may be generated based on the MPD file, the subset of the plurality of media segments of the media content that is stored within the cache of the middle box platform, and/or the available bandwidth on the backhaul link. The dynamic MPD file may be transmitted to the client.
