PURPOSE:To attain the ease of the correction of an address list by providing an address server storing the address data of all terminal stations to each local area network sub system so as to retrieve the address server. CONSTITUTION:Plural local area network sub systems LAN1-LANn are connected via node stations N1, N2-. The sub systems LAN1-LANn are provided respectively with plural terminal stations S11-S1m,-,Sn1-Snm and address servers S1A-SnA, and each address server stores a list for sub system names belonging to all terminal stations are addresses specific to each terminal station. When the address of an opposite terminal station desired for transmission is not clear to a terminal station, the address server is retrieved and the data is transmitted after the opposite address is obtained. Thus, the memory area of each terminal station is saved and the correction jib of the address table at increase/decrease in the terminal station attended with the system change is simplified.
