摘要： PROBLEM TO BE SOLVED: To provide a LAN repeater capable of avoiding operational abnormality caused by version mismatching between data loaded to equipment on one LAN side and the data loaded to equipment on the other LAN side.
SOLUTION: A first reception means 11 of a LAN repeater 10 receives version information of data loaded to equipment from the equipment on the side of a trunk LAN 20 and a second reception means 13 receives version information of data from equipment on the side of a base LAN 30. A control means 15 compares the received version information to each other and controls the continuation and stop of relay processing in accordance with a result of the comparison. For example, if the version information agrees completely, the data are relayed; and when there is mismatching, relay processing is stopped. Alternatively, if high-order digits are agree, regardless of whether low-order digits of the version information agree, the data are relayed; and if high-order digits do not agree, relay processing is stopped.
