Abstract
In a satellite communication system comprising at least a hub and a plurality of terminals, at least one terminal may include a cache for storing data objects. The cache may be based on a detachable memory device that may be inserted to or removed from the terminal at any given time, including after the terminal is deployed. Aspects are directed to preventing a prefetching of objects already stored in a cache of a remote terminal. In some embodiments, an efficient multicasting of content to terminals over an adaptive link may occur in a manner which may benefit terminals comprising a cache while not affecting or minimally affecting the performance of terminals that may not include a cache.
