Abstract
The problems of an additional load to an AR having the function of transferring a packet, a BR functioning as a border relay device, and an address management server, a packet loss due to an unnecessary inquiry to the management server, an increasing delay of a packet transfer, etc. can be reduced. According to the address identification information for identification of the type of an address, routers determine to which type the address assigned to a given packet belongs, a terminal identification address for identification of a source terminal and a destination terminal, a packet transfer address for transfer of the packet to another router, or an address requiring no address conversion. Thus, an address conversion network connected to an external IP network can be realized, an increased load by an inquiry about an erroneous address, etc. and a packet loss and delay due to an unnecessary inquiry can be reduced.
