Abstract

An approach for providing intelligent caching is disclosed. A communications system includes a first caching logic that is configured to analyze a traffic stream for content and to output a first profile of the content. The system also includes a second caching logic that is configured to generate a second profile based upon the first profile, wherein the second profile is used to retrieve content. The content associated with the second profile may be pre-loaded into remote cache using multicasting over a wide area network (WAN), such as, a satellite network.
