Abstract:
1. A node information management system, comprising: a plurality of nodes connected via transmission links; and a collecting apparatus which is connected with said plurality of nodes and collects respective node information from said plurality of nodes, wherein said plurality of nodes include first and second nodes, said second node serving as a backup node for storing first node information about said first node as first backup information, wherein said first node comprises a first node information generating section to generate said first node information, a first node information storing section to store said first node information, and a first management section to make said first node information storing section store said first node information and to send said first node information to said second node, wherein said second node has a first backup information storing section to store said first node information, and wherein said collecting apparatus, if it judges that said first node information cannot be collected from said first node, collects said first node information from said second node on the basis of a correspondence relation between said first node and said second node.
