PROBLEM TO BE SOLVED: To freely select networks and to select favorable network according to a communication state and communication quality by connecting a terminal connection physical terminal and any of network connection physical terminals in each packet, that is inputted from a data communication terminal based on a control signal from the data communication terminal. SOLUTION: When a terminal communicating part 201 is given a control signal that includes packet switch changeover information from a data communication terminal, it stores the packet switch changeover information in a packet switch changeover table 202. Here, the packet switch changeover information is one that associates prescribed information which is added to a packet with a physical terminal (output terminal of a switch part 303, if directly) of each network 131,..., 13N. In other words, the packet switch changeover information associates the prescribed information that is assigned to a packet with each network 131,..., 13N. |
