Abstract

A system and method for effectively supporting content distribution in an electronic network includes a content server and a peer-to-peer network of client devices. The content server stores content items received from a content provider. A recommendation engine of the content server creates a global recommendation list to identify an optimal global candidate from among the stored content items for performing an automatic and transparent content download procedure. The recommendation engine creates the global recommendation list by analyzing selectable content-ranking criteria from a plurality of device users of the client devices. The content server then downloads the optimal global candidate from the stored content items to one or more identified target devices during the content download procedure.

19. The system of claim 18 wherein a communication manager of said content server automatically and transparently performs said content download procedure to push said optimal global candidate from said global recommendation list to said target client devices.

20. The system of claim 19 wherein a profile manager of said content server performs a profile update procedure to update said client profiles to reflect any recent download activity or other information changes in said electronic network.

21. A method for supporting content distribution in an electronic network, comprising the steps of:

storing content items received from a content provider into a content server;

utilizing a recommendation engine to create a global recommendation list that identifies an optimal global candidate from among said content items for performing a content download procedure; and

connecting client devices to said content server through said electronic network, said content server downloading said optimal global candidate to one or more target devices of said client devices during said content download procedure.

22. The method of claim 21 wherein said client devices are configured in a peer-to-peer network that supports direct bi-directional communications between any of said client devices.
