STORAGE INSTRUCTION DEVICE, NODE DEVICE, STORAGE INSTRUCTION PROCESSING PROGRAM, NODE PROCESSING PROGRAM AND STORAGE INSTRUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a storage instruction device, a node device, a storage instruction processing program, a node processing program and a storage instruction method, wherein it is estimated that a node device having a short participation period in a content distribution storage system has small free recording capacity in a storage part such as an HD (a hard disk) when putting content data into the content distribution storage system and wherein storage is instructed to the node device having the short participation period.;SOLUTION: The storage instruction device in the content distribution storage system includes a storage instruction device, which makes the content data be stored in the node devices, for use of a plurality of pieces of the content data between the plurality of node devices communicable with each other via a network. The storage instruction device selects a first prescribed number of the node devices each having shorter participation period wherein the node device participates in the content distribution storage system, based on node information stored in a node information storage means, and sends out storage instruction information for instructing the storage of the content data.;COPYRIGHT: (C)2010,JPO&INPIT
