<p><P>PROBLEM TO BE SOLVED: To provide a technique for suitably relaying communication data. <P>SOLUTION: In a communication controller 10, comprising a receiving circuit which converts a received signal into a data train, a plurality of ports for connections with a plurality of networks, a database stored with an IP address of a communication device and a port, to which communication data to be transmitted to the communication device should be output in a correspondence state, a retrieval circuit which retrieves an IP address of a communication device as the destination of the acquired communication data from the database, and a processing executing circuit which sends out the communication data from the port made to correspond to the IP address of the communication device as the destination of the communication data, a PHY processing unit 5a omits processing of confirming whether the address of the destination is the address of the communication controller itself and supplies the acquired communication data to the retrieval circuit. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
