<p>PROBLEM TO BE SOLVED: To maintain a network system by conducting monitor of a state of a memory and a communication equipment, providing an RAS section that bypasses packets to other node and disconnecting a node on the occurrence of a fault including a power failure from the network. SOLUTION: The device diagnoses, and monitors a state of RMU 12a-12c and each of the RMU 12a-12c is provided with each of RAS sections 14a-14c which bypass a packet received by link control sections 17a-17c to other node directly on the occurrence of a fault including power failure. Thus, data are copied and shared in common without notifying communication by CPU 11a-11c and a network ring is maintained even on the occurrence of a fault of a node or a power failure, then other node utilizes the RMU 12a-12c independently of the fault.</p> |
