20090055506  Centralized selection of peers as media data sources in a dispersed peer network 26 February 2009 Inventors:  Michael D. Hudson  Brian L. Windheim  Darin Stewart  Sudhir Menon  Mark W. Goschie  Glen Curtis Shipley Agents:  KENYON & KENYON LLPOrigin: NEW YORK, NY USIPC8 Class: AG06F1516FIUSPC Class: 709208 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. 20090049185  System and methods of streamlining media files from a dispersed peer network to maintain quality of service19 February 2009 Inventors:  Michael D. Hudson  Brian L. Windheim  Darin Stewart  Sudhir Menon  Mark W. Goschie  Glen Curtis ShipleyAgents:  KENYON & KENYON LLPOrigin: NEW YORK, NY USIPC8 Class: AG06F1516FIUSPC Class: 709231 Abstract: Media content, including content suitable for streaming, is distributed to and accessible over a communications network by computer nodes within a peer storage network of computer nodes hosting respective content stores. Discrete portions of a content file are multiply distributed to and persisted in a distributed set of the content stores existing within the storage network such that various content stores persist subsets of the content file portions. A computer node retrieves the discrete portions of the content file from the various distributed content stores, depending on node availability, the particular discrete portions there available, and node and network performance factors sufficient to maintain a minimum quality of service, thereby enabling streaming presentation of the content file on the requesting computer node.
