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。
