Abstract

An inter-local area network (LAN) connecting system in which LANs are connected to an asynchronous transfer mode (ATM) switching network by respective bridge devices to effect communication between terminals connected to different LANs through the bridge devices and the switching network. Logical connections are set between the bridge devices in advance to transfer cells, which are information units of data transfer. Each of the bridge devices has a first address table on which the addresses of terminals connected to a LAN accommodated in this bridge device are registered and held by learning, a second address table on which the addresses of terminals connected to LANs accommodated in other bridge devices are registered and held by learning in pairs with identifiers that identify logical connections between this bridge device and the other bridge devices, and means for checking the identifier of a received information frame or received cell against the first or second address table to judge the destination in accordance with the registration condition of the first or second address table, and effecting communication on the basis of the result of the judgement.
