<p><P>PROBLEM TO BE SOLVED: To provide a technique for raising efficiency of communication by eliminating unnecessary processing. <P>SOLUTION: A communication controller includes: a plurality of ports for transmitting communication data; a first database 50 in which identification information of the transmission destination of communication data and an output port for outputting the communication data to be transmitted to the transmission destination are associated with and stored; a retrieval circuit 30 which retrieves the identification information of the transmission destination of the acquired communication data from the first database 50; a processing execution circuit 40 which sends the communication data from the port associated with the identification information of the destination of the communication data; and an output control unit which controls the output of the communication data according to communication speeds of networks connected to the plurality of output ports. The communication controller includes a plurality of databases for a plurality of different kinds of communication control as the first database 50 and a second database 60, and a switching unit 180 which enables the communication controller to achieve the plurality of different kinds of communication control by switching the database. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
