Abstract
An information obtaining unit () of a monitoring apparatus () obtains from each node, topology map information created in each node by an exchange of information and sharing of information between nodes that belong to a ring network. The topology map information is information that indicates a connection relation between the nodes in the ring network. A topology comparison unit () of the monitoring apparatus () compares the topology map information obtained from each node by the information obtaining unit () with topology definition information retained in a memory () beforehand, and determines whether or not a configuration of the ring network is according to design. The topology definition information is information that defines the connection relation between the nodes in the ring network.
