Claim Text:
1. A packet forwarding device that performs forwarding of a packet between first and second wireless communication networks to which different identifiers are attached, the first wireless communication network being connected to a main network, the packet forwarding device comprising: a relay network that is interposed between the first and second wireless communication networks; a first processing unit that is connected to the first wireless communication network, the first processing unit performing first routing control by using first routing information in which either one of the main network and a wireless communication network is defined as an outgoing interface for each ending point address of the packet, analyzing the main network defined in the first routing information as the relay network, and analyzing the wireless communication network defined in the first routing information as the first wireless communication network; and a second processing unit that is connected to the second wireless communication network, the second processing unit performing second routing control by using second routing information in which either one of the main network and a wireless communication network is defined as an outgoing interface for each ending point address of the packet, analyzing the main network defined in the second routing information as the relay network, and analyzing the wireless communication network defined in the second routing information as the second wireless communication network.
