摘要： Methods and apparatuses to manage network resources across a group of playback devices that share the same resources to control video quality across the group of playback devices are provided. A central controller collects information about a plurality of playback devices wherein the playback devices share a network resource. The central controller also collects information regarding the network resource. The central controller allocates the network resource to deliver one or more requested video segments to one or more playback devices based on the information collected from the plurality of playback devices and the information collected regarding the network resource. By providing a central controller that is aware of the available network resources and the needs of the playback devices, the network resource can be managed in a way that improves the quality of experience for end users across all the playback devices while maximizing the efficiency of the network resources.

摘要： Techniques for assessing the cost of allocation of execution and affecting the allocation of execution are disclosed. The cost of allocation of execution to or between a first computing device (e.g., a mobile device) and one or more computing resource providers (e.g., one or more Clouds) can be determined during runtime of the executable code. It will be appreciated that a computing system can operate independently of the first computing device and one or more computing resource providers and provide execution allocation cost assessment as a service to the first computing device and/or one or more computing resource providers. Execution allocation cost can be assessed (or determined) based on execution allocation data pertaining to the first computing device and/or one or more computing resource providers. By way of example, power consumption of a mobile device can be used as a factor in determining how to allocate individual components of an application program (e.g., weblets) between a mobile phone and a Cloud. The invention is especially suited for Elastic computing environment and systems. In an Elastic computing environment, scalable and dynamic external computing resources can be used in order to effectively extend the computing capabilities beyond that which can be provided by internal computing resources of a computing system or environment.

摘要： Cache management techniques are described for a content distribution network (CDN), for example, a video on demand (VOD) system supporting user requests and delivery of video content. A preferred cache size may be calculated for one or more cache devices in the CDN, for example, based on a maximum cache memory size, a bandwidth availability associated with the CDN, and a title dispersion calculation determined by the user requests within the CDN. After establishing the cache with a set of assets (e.g., video content), an asset replacement algorithm may be executed at one or more cache devices in the CDN. When a determination is made that a new asset should be added to a full cache, a multi-factor comparative analysis may be performed on the assets currently residing in the cache, comparing the popularity and size of assets and combinations of assets, along with other factors to determine which assets should be replaced in the cache device.
摘要翻译：描述了用于内容分发网络（CDN）的缓存管理技术，例如支持用户请求和视频内容传送的视频点播（VOD）系统。可以例如基于最大高速缓冲存储器大小，与CDN相关联的带宽可用性以及由CDN内的用户请求确定的标题色散计算，为CDN中的一个或多个高速缓存设备计算优选高速缓存大小。在用一组资产（例如，视频内容）建立高速缓存之后，可以在CDN中的一个或多个高速缓存设备上执行资产置换算法。当确定将新资产添加到完整缓存时，可以对当前驻留在缓存中的资产执行多因素比较分析，比较资产的流行度和大小以及资产组合以及其他确定在缓存设备中应该替换哪些资产的因素。

摘要： The present invention provides a content locating method and a content delivery network node. In this case, the content locating method provided by the present invention comprises: receiving by a first content delivery network CDN node a service request sent by a service control function entity or an IPTV service control function entity, wherein this service request carries a content identifier which is used to indicate requesting content corresponding to this content identifier; if the first CDN node cannot provide the content service requested by the service request, then the first CDN node sends an inquiry request to a CDN global controller so as to acquire the information about a second CDN node which can provide the content service requested by the service request and request the second CDN node to provide the content service. By way of the present invention, the pressure of the CDN global controller can be reduced and the processing delay of CDN can be shortened.

摘要： A method of data management for efficiently storing and retrieving data in response to user access requests. The method includes receiving a request from at least one client for a title not resident in a storage server, where the title includes a play track having a plurality of chapters. The retrieval from a secondary storage device of play track portions proximate chapter delineation points is initiated, and bandwidth capacity and quality-of-service (QoS) parameters associated with the secondary storage device is determined. In the case of a client request to begin presentation of the title at one of the chapters, streaming of retrieved portions of the play track chapter to the client is initiated, masking latency associated with the secondary storage device is provided, and retrieval of at least unretrieved portions of the play track chapter and subsequent play track portions from the secondary storage device is initiated.

摘要： A content distribution network (CDN) system is disclosed, where the system includes a content distribution device and at least one media server. Storage media with different characteristics are mounted on the media server or storage media with different characteristics are mounted on media servers. The content distribution device is configured to select a storage medium for content according to a mapping relationship between the attributes of the content and the characteristics of the storage medium, and distribute the content to the storage medium through the media server on which the storage medium is mounted. A content distribution method and a content distribution device are also provided. Because the content of different types is distributed to storage media with different characteristics, the cost of the storage medium in the CDN system is reduced, and the storage utilization ratio is increased.
