摘要： A method, system and related apparatus are described, the system comprising a caching-capable element which is part of a data network, which receives a request from a downstream client device, the request including a content request, the content request including a Universal Resource Identifier (URI) and an explicit caching request, the caching request includes a unique content identifier which is independent of the URI, and optional expiration date information, a comparator included at the caching-capable element which compares the caching request against the existing cached content, and if the requested content is cached then the caching-capable element forwards the cached copy of the requested content to the client device, and if the requested content is not cached, then the caching-capable element forwards the request to a further upstream device, and, upon reception of the requested content from the further upstream device, returns the requested content to the requesting downstream device, and caches the requested content for further distribution to other clients. Related methods, systems and apparatus are also described.
摘要翻译：描述了一种方法，系统和相关装置，该系统包括作为数据网络的一部分的可高速缓存元素，其从数据网络接收来自下游客户端设备的请求，该请求包括内容请求，该内容请求包括统一资源标识符（URI）和显式高速缓存请求，高速缓存请求包括独立于URI的唯一内容标识符以及可选的过期日期信息，在可高速缓存的元素上包括的比较器，该比较器将高速缓存请求与现有高速缓存的内容进行比较，并且如果所请求的内容被高速缓存，则具有高速缓存能力的元件将所请求的内容的高速缓存副本转发给客户端设备，并且如果所请求的内容未被高速缓存，则可高速缓存元件将该请求转发给另一上游设备，并且在从所述另一上游设备接收到所请求的内容时，将所请求的内容返回到所述请求下行链路 m设备，并缓存所请求的内容以便进一步分发给其他客户端。还描述了相关的方法，系统和设备。
