<p>PROBLEM TO BE SOLVED: To provide a communication terminal that inexpensively transmits information to a transmission destination without tracing an undesirable path even in the case of transmitting the information via a communication terminal having a relay function. SOLUTION: A main control section 1 stores the least expensive routing to a connection path information table 24 according to connection information sent from other communication terminal in advance. In the case of transmitting information to a transmission destination, the least expensive routing is used in the connection path information table 24 to select a relay path. In this case, the importance of the transmitted information or the like is taken into account and in the case of transmitting, e.g. secret information, a path such as the Internet where leakage of secrecy may take place is avoided through the selection of a relay path. Then the information with information relating to the relay path and denoting whether or not he information is secret added thereto is transmitted to a succeeding communication terminal having a relay function.</p> |
