In the figure, the network management system 1 and the network management system 2 have the same configuration, and have an active / standby redundant relationship in internal configuration units. The network management system 1 includes an application A storage unit 11 storing an application program group A, an application B storage unit 13 storing an application program group B, a management data A unit 12 storing management data on the network side, and a management data B. The control unit 15 includes a unit 13 and a control unit 15 that performs management on the network side by using the above application program and management data unit and simultaneously monitors the active system and outputs a switching signal 101 when an abnormality is detected. .

The application A storage unit 11 and the management data A unit operate as an active system that always operates, and the application B storage unit 13 and the management data B unit 14 operate as a standby system that is always on standby. Further, the network management unit 2 has the same configuration, though the active system and the standby system are opposite.

The network is composed of a plurality of managed devices 4 using the Ethernet 3 as a transmission path. Two network management systems 1 and 2 are also Ethernet 1
4 and is used to send and receive necessary data between two network management systems or managed devices via this Ethernet 14.
