Abstract
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.
