<P>PROBLEM TO BE SOLVED: To provide a technique for preventing generation of a trouble caused by overlapping specific information in a communication apparatus serving as a communication node that constitutes a communication system communicating between a plurality of communication nodes connected to a common communication wire. <P>SOLUTION: An ECU in a communication system determines whether or not specific information attached to data transmitted from other communication nodes coincide with specific information for identifying a self (S120, S130). When the respective specific information coincide with each other, overlapping of the specific information is output (S140, S150, S210, S230). Such an ECU can detect that the self specific information overlaps specific information of other communication nodes and output it; therefore, by taking measures not to overlap the specific information according to the output, a trouble caused by the overlapping of the specific information can be eliminated. <P>COPYRIGHT: (C)2012,JPO&INPIT |
