    摘要： A content delivery method and a system based on popularity-driven pre-provisioning of content in a content delivery network CDN (102, 202). In one method, a network element (118, 212, 400) may obtain (502 A) trend data, relative to a particular content to be distributed by the CDN. The network element may also obtain (502B) demographic data of subscribers serviced by the CDN. An expected popularity distribution of the particular content is forecasted (504) based on a metric derived from, at least one of the trend data and the demographic data. A push policy for pushing and/or pre-provisioning of the content to one or more nodes of the CDN is effectuated (506) at the network element based on the expected popularity distribution of the content relative to the geographical region serviced by the CDN.

    摘要： In one embodiment of a network pipe optimization method, a network element (122, 400, 1002) may obtain (1108) at least one of a push pipe utilization report and a pull pipe utilization, report from each distribution node of a content delivery network ( 102, 202, 250). Based on the utilization reports, the network, element may determine (1114) new push pipe weights and new pull pipe weights for distribution pipes associated with each distribution, node of the content delivery network. Using at least one of the new push pipe weights and new pull pipe weights, a network pipe utilization model associated with the content delivery network may be simulated (1116), Responsive to determining (1118) that the simulated network pipe utilization model yields an improved utilization of the content delivery network, the new push pipe weights and new pull pipe weights may be distributed (1120) to each distribution node in the content delivery network.

    摘要： A system and method for optimizing defragmentation of content in a content delivery network (CDN). In an example, a manifest available to the content delivery node with respect to a particular content as well as segment files stored in a database cache of the content delivery node are analyzed to determine if any segment files referenced by the manifest are absent from the database cache. If so, one or more delivery rules associated with the content delivery node based on historical ABR asset delivery patterns may be applied to determine representations of the absent segment files that satisfy the one or more delivery rules. After determining compliant representations of the absent segment files, they may be pulled from another content delivery node of the CDN (e.g., a parent node or an edge server node).

    摘要： A system and method that utilize a learning system to maintain a set of geographical locations indicating an area where network data coverage is poor. When it is determined that a client device is moving towards such an area, the client is forced or instructed to switch to a lower delivery bitrate for video segments in order to force the client's Adaptive Bit Rate (ABR) playback buffer to fill itself with enough low-quality video segments to enable the client to cross the area without video playback interruption. Thus, the client mobile device may be preemptively forced to choose the lowest bitrate specified in a manifest file for the delivered video segments as the bitrate for downloading video segments when approaching the poor coverage area. Hence, the client device can maintain a minimum level of Quality of Service (QoS) when moving through network areas with poor data coverage.

    摘要： A streaming policy management system and method wherein bandwidth may be allocated based on external device information received from a streaming client device connected to one or more external audio/video (A/V) devices. When a streaming network back office receives a request from the streaming client device for delivery of a particular content, wherein the request includes external device information of one or more external A/V devices connected to the streaming client device, a bandwidth is determined for streaming the particular content to the streaming client device and a request may be made to a content delivery network to create a distribution pipe having the bandwidth to accommodate the delivery of the particular content. A manifest file is provided to the streaming client device that includes one or more pointers that point to content segments of the particular content.
