Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a node device, a node processing program, and a content data storage method for determining whether or not there exists any free capacity in a cache of another node device, and for improving the use efficiency of the cache as a whole peer-to-peer type communication system. SOLUTION: Whether or not there exists any node device whose free recording capacity is equal to or more than a prescribed value among node devices Nn described in a routing table or an index cache is determined. A replica determined to be deleted by the node device is transmitted to the node device whose free recording capacity is equal to or more than the prescribed value. COPYRIGHT: (C)2011,JPO&INPIT
