CONTENT DISTRIBUTION SYSTEM, CONTENT DISTRIBUTION PROGRAM FOR MANAGEMENT SERVER, AND CONTENT DISTRIBUTION PROGRAM FOR CLIENT

PROBLEM TO BE SOLVED: To quickly and efficiently distribute large capacity of data under unitary management to a plurality of users. SOLUTION: A management server 10 stores distribution schedule, distribution control information, supplier information, and the address information of a client 20. A client 20A specifies content data to be distributed based on feed information acquired from the management server 10, and acquires the distribution control information and supplier information of the content data from the management server 10, and notifies a management server 10 of the download start of the content data whose request destination has been specified. The management server 10 notifies a client 20B as the request destination of inter-peer communication information (address information) with the client 20A. The client 20B transmits the fragmented content data to the client 20A based on the inter-peer communication information. The client 20A checks reception data, and requests retransmission when the reception data are imperfect, and stores the reception data when perfect. COPYRIGHT: (C)2009,JPO&INPIT
