Information communication program, information communication apparatus and information communication method

摘要

An information communication program, an information communication apparatus and an information communication method make it possible for a mobile node to maintain direct communication with some other terminal while it is moving from a network to another if the some other terminal is always located on a particular network. An information communication program for causing a computer to execute an operation of controlling an information communication apparatus having a static address and a dynamic address comprises a receiving party's address determining step that determines the address of the party receiving the packets delivered from an application of the information communication apparatus according to the address information of the packets to be transmitted and the address information of a predetermined subnet in order to transmit them to the receiving party and an encapsulating step that encapsulates the packets to be transmitted so as to transmit them by way of the relay apparatus when the receiving party's address is the first subnet.
