<p><P>PROBLEM TO BE SOLVED: To provide a node device and the like for performing communication in a tree structure. <P>SOLUTION: The storage unit 602 of the node device 601 stores a node name sequence as an own path name, stores zero or more pair of a node name and a communication identifier as a pair of a slave node name and a slave ID, and stores one communication identifier as a master ID. A receiving unit 603 receives data received from another node device in which the node name sequence is designated as a destination path name. If the own path name matches the destination path name, an output unit 604 outputs the data. A transmitting unit 605 transmits the data to the other node device correlated to the slave ID of the pair if one in which the slave node of the pair is added to the own path name matches the head or all portion of the destination path name for any one of the stored pairs, and the unit 605 transmits the data to the other node device correlated to the stored master ID if the own path name does not match the head or the all portion of the destination path name. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
