Abstract
A LAN emulation system is capable of avoiding a fault without making a line dual by a local dual structure on the premise that a LAN emulation server is made dual. An ATM switch, to which a LAN emulation terminal is connected, is provided with a line fault detecting unit, a routing table in which to define a correspondence a specified address to a line, and a line status table rewritten based on a result of detection by the fault detecting unit. A LAN emulation configuration server (LECS) connected to the ATM switch is constructed to have a dual structure. If a fault occurs in a connection to the LAN emulation configuration server, it is feasible to easily implement a connection to the dual LAN emulation configuration server and, because of no necessity for making dual the line itself, to easily construct a fault avoiding system.
