An exchange apparatus is disclosed, that comprises an address solving port for extracting logical address information from a datagram received from an Internet protocol computer network through a data transmission path and converting the extracted address information into absolute address information of an asynchronous transfer mode network, an address converting port for converting the absolute address information converted by the address solving port into an address having a geographically hierarchical structure and adding the converted address information to the original datagram, an ATM cell assembling port for assembling an ATM cell that is transferred at a time in the asynchronous transfer mode with the data gram containing the address information added by the address converting port, and a transfer destination setting and outputting port for setting a virtual path and a virtual channel that represent the transfer destination to the ATM cell assembled by the ATM cell assembling port and outputting the resultant ATM cell to the asynchronous transfer mode network. <IMAGE> |
