摘要： A remote site downloading system is disclosed in which a local computer establishes a session with a content server, and a content file and geographic destination drive are selected. The local computer is typically on a first access network and the user wishes to have the file downloaded to a geographic drive, i.e., a remote site computer whose location and other properties are mapped in a mapping file on the local computer. The geographic drive is usually on a different access network in a dynamic location such as a hotspot or a fixed location such as broadband cable or DSL. The local computer is specially programmed to allow selection of the geographic target drive, pack information comprising cookies and a URL, and sends it to the remote geographic drive computer, where it may act as a proxy to cause downloading from the content server to the geographic drive on the remote site computer.

摘要： A system and method schedules downloading of content files from a content server to a client through a cache server. A user can request a content file for future delivery at a certain service time at a certain location such as a hotspot. A cache server receives these requests and sorts them in an order which depends on the relative service times, and eliminates redundancies by only downloading content files not already stored in the cache server. A scheduling algorithm minimizes the instances of tardiness under the constraint of cache storage capacity.
摘要翻译：系统和方法通过缓存服务器安排将内容文件从内容服务器下载到客户端。用户可以在某个特定位置（例如热点）的特定服务时间请求内容文件以供将来传送。高速缓存服务器接收这些请求并按照相对服务时间的顺序进行排序，并通过仅下载尚未存储在缓存服务器中的内容文件来消除冗余。调度算法在高速缓存存储容量的约束下最小化迟到的情况。

摘要： Remote site downloading of content to a hotspot occurs by way of a cache server, which, when networked the hotspot, processes download, order proxies received from remote content provider servers or content user mobile devices. The cache server stores content files downloaded over the Internet from the content provider servers according to the proxies, and delivers content files to the appropriate mobile devices when they sign in at the hotspot. For example, a set top box at a hotspot can receive an instant message which includes a data set, including cookies, from a personal data assistant. There after, the set top box can download a movie from a movie vendor web site which has been previously ordered and paid for by a user using the personal data assistant over a cellular network, and then wirelessly transmit the movie to the personal data assistant using Wi-Fi protocol when it arrives at the hotspot and is authenticated.

摘要： The downloading of content to a requesting client (A1, A2 and A3) through content distribution network consisting of edge servers occurs upon receiving a content request, a content server responses with a request-routing message that includes source data identifying the content and path data identifying a path through the network to a source of such content. Having the path information in request-routing message enables a requesting client to make the request to a particular edge server, which in turn can register the downloading request and access the content from an appropriate location, thereby obviating the frequent communication between the content server and edge servers on the path.
摘要翻译：通过由边缘服务器组成的内容分发网络将内容下载到请求客户端（A1，A2和A3），在接收到内容请求时发生内容服务器响应，请求路由消息包括标识内容和路径数据的源数据识别通过网络到这样的内容的源的路径。在请求路由消息中具有路径信息使得请求客户端能够向特定边缘服务器发出请求，该特定边缘服务器又可以注册下载请求并从适当位置访问该内容，从而避免了内容服务器与路径上的边缘服务器。
