Abstract
A hierarchical content distribution system includes a seeding server, a plurality of geographically distributed content platforms, and a distribution controller, all interconnected by a communications network. The seeding server initially receives content files for distribution to various content platforms that provide for the persistent storage of the content files. Each content platform includes a content file server responsive on-demand to requests for the transfer of content files. The distribution controller autonomously monitors the transfers of content files and selectively issues transfer directives to the content platforms to modify the distribution of content files among the content platforms. The content file servers respond to received transfer directives by issuing requests for the transfer of the directive identified content files, thereby conforming the specific distribution of content files to an optimal distribution pattern as determined by the distribution controller based on usage patterns.
