PROBLEM TO BE SOLVED: To further improve probability that divided sub-data are read from each node, to restore original data than a conventional manner. SOLUTION: This invention is achieved in a distribution system in which a plurality of nodes connected to a peer-to-peer network executes the distributed storage or distributed processing of data. For example, this system includes a management means, extraction means and request means or the like. The management means manages the on-line rate or conduction rate of one or more nodes among the plurality of nodes. Also, the extraction means compares the on-line rate or conduction rate of each node to extract the specific number of nodes whose on-line rate or conduction rate is relatively high. Furthermore, the request means requests the distributed storage or distributed processing of the data to the extracted nodes. COPYRIGHT: (C)2008,JPO&INPIT
