<p>PROBLEM TO BE SOLVED: To transmit and receive communication data by routing with secrecy with respect to a router as an inter-network connecting device for deciding the path of a datagram by an internet protocol. SOLUTION: A routing module designates a routing destination IP(internet protocol) address from a transmission destination network address and an arbitrarily set routing identifier based on a routing table, and transmits an IP datagram received from the IP module and this routing destination IP address to a prescribed IP module. It is constituted so that this routing table uses a value which masks this identifier.</p> |
