摘要： For delivering an audio and/or video content using adaptive streaming from a cache server to a client device, the audio and/or video content being segmented into data segments available in various representations with respective audio and/or video qualities, the representations being time-aligned per segment, the segments being further divided into chunks, a method comprises: obtaining a round-trip time value applicable between the cache server and the client device; computing a minimum bulk transfer size from the maximum average bitrate of the various representations of the audio and/or video content and from the obtained round-trip time value; computing a minimum bulk duration, with respect to the audio and/or video content, for the representation to be delivered to the client device; and delivering the audio and/or video content by burst transfers in the form of bulks of aggregated successive chunks for each segment in accordance with the computed minimum bulk duration.

摘要： An audio and/or video content delivery system (100) is deployed on top of a mobile network, and comprises plural cache servers (132) arranged using a layer-based hierarchical tree topology. A breakout function of aggregation nodes (130) of the mobile network enables routing to the cache servers (132) packets addressed to an anycast addressing associated with the cache servers (132), wherein each layer of the layer-based hierarchical tree topology is associated with an anycast addressing. Traffic steering is configured so that the breakout function in each layer routes traffic addressed to the anycast addressing associated with said layer to the cache server (132) of said layer as well as of any and all downstream layers, in order to ensure service continuity for delivering an audio and/or video content to a mobile terminal (150).
