<p><P>PROBLEM TO BE SOLVED: To provide a system capable of dynamically setting relay of data between networks connected to each other via the Internet in response to a request from an individual terminal. <P>SOLUTION: Upon receiving a relay instruction for designating a relay apparatus 25 from a communication apparatus 11 (S703), a relay apparatus 15 requests a state notice from a server 35 (S704), and upon receiving a notice that a relay apparatus 25 has logged in (S711), the relay apparatus 15 transmits a connection request to the server 35 (S715). In this way, the relay apparatus 15 establishes a TCP connection with the relay apparatus 25 (S719). Upon newly receiving a relay instruction for designating the relay apparatus 25 from a communication apparatus 12 (S725), since an already established connection is used, the relay apparatus 15 gives a response that relay can be available (S726). Then, the relay apparatus 15 relays the data transmitted from the communication apparatus 12 to the relay apparatus 25, utilizing the TCP connection same as the connection utilized by the communication apparatus 11 (S728). <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
