<p><P>PROBLEM TO BE SOLVED: To form a plurality of relay nodes capable of constructing a new communication network, without the problem wherein the increase of traffic other than traffic of communication information is induced, to bring about the reduction of communication efficiency, or the like. <P>SOLUTION: A communication apparatus has an interface part 12 and a core part 13. Header data included in framed data, based on a communication signal received from the interface part 12 is sent to the core part 13, and the core part 13 performs header processing of comparing the header data with history data in a history database and adding a flag according with a comparison result to the header data, and the header data after the header processing is sent back to the interface part 12. The interface part 12 changes identification information in original framed data, in accordance with the flag added to the header data after header processing, and an output communication signal, based on the framed data wherein the identification information has been changed is transmitted. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
