<p>Upon executing data exchange between a pair of LAN's(3, 5) via a gate way(11), a root hub(RH1-RH6) transmits the communication data, in an address describing area of which source/destination addresses are described, and a gate way(11) decodes the source/destination addresses included in received communication data, decides whether or not the source and the destination belong to the same LAN based on decoded source/destination addresses and attribution identification information, selects an appropriate route as the destination of the communication data based on a result of this attribution decision, and then transmits the communication data to the destination via selected route. <IMAGE></p> |
