ABSTRACT:
A first communication terminal broadcasts an ARP request frame which includes an IP address to a network, a second communication terminal which has the identical IP address to the one included in the ARP request frame transmits an ARP response frame which is added with a MAC address, to a second ATM terminal adapter, then the second ATM terminal adapter temporarily stores the ARP response frame. The second ATM terminal adapter broadcasts a virtual path request frame to a first ATM terminal adapter, and branching units which are in a relaying path are specified in accordance with interface information. Then, after a virtual path response frame is transmitted to the second ATM terminal adapter by following back the branching units which are specified during the virtual path request frame was transmitted, the temporarily stored ARP response is transmitted to the first communication terminal, thereby easily setting a most effective relaying path while exchanging information via LANs which are connected to an ATM network.
