Abstract: PURPOSE: A packet processing method in a redundant network system and a system thereof are provided to enhance an algorithm for checking redundancy in a receiving terminal to minimize packet loss, thereby building a reliable network system. CONSTITUTION: A transmitting terminal transmits the same packet through a redundant network made of the first and second networks. If the nth packet is received through the first network, the nth number of the nth packet is compared with (n-1)th number of the (n-1)th packet(S300,S310). If the (n-1)th number and the nth number are not serial numbers, the nth packet is buffered during a fixed period. The buffered nth packet is transmitted to a higher layer.

Abstract: PURPOSE: A method and a device for restoring the network with a link bypass mode are provided to minimize data loss by continuously using two links through bypass even if failure occurs when a frame is transmitted. CONSTITUTION: A plurality of switchses(300a-300n,310a-310n) perform a normal operation or a backup switch function depending on a control signal when the normal operation is performed or failure occurs when the same frame is transmitted by using two links. A bypass transmission controller(220) transmits the frame through the backup switch set to the failed switch if the failure occurs in the link. The backup switch is selected by referring to a path table.
