<P>PROBLEM TO BE SOLVED: To provide a node device capable of avoiding a useless excess of a communication load. <P>SOLUTION: A node device 1000 constitutes a plurality of node devices connected in a circular manner with a plurality of other node devices. The node device stores a table having destination identification information associated with communication link identification information (1001), and on detecting the occurrence of a failure on a failed communication link (1003), the node device transmits to another node device a modification data, including transmission source identification information to identify the self-node device, through a communication link other than the failed communication link (1004). If a communication link associated with destination identification information identical to the transmission source identification information, included in the modification data received from another node device, is different from a communication link (communication link at the time of reception) used to receive the modification data, the node device modifies the communication link identification information, associated with the destination identification information, to communication link identification information of the communication link at the time of reception (1005). <P>COPYRIGHT: (C)2013,JPO&INPIT |
