Abstract
There is installed a special management node to efficiently perform network configuration management. When a node starts communication with another node, the node sends a request for node position information about the communication counterpart node to a management node. Upon receiving the node position information request, the management node references a network configuration information table to calculate information about a route from the node to the communication counterpart node. The management node notifies the calculated route information. By utilizing the route information, the node can communicate with the communication counterpart node. Each node notifies node-to-node connection information, information about links with adjacent nodes, to the management node as necessary. When a newly connecting node requests an optimum connection target from the management node, the management node selects an optimum node to connect to, based on network configuration information it holds and notifies it to the newly connecting node. The newly connecting node connects to the optimum node in accordance with the contents of the notified information.

11. A network configuration management method for storing, holding and managing network configuration information indicating connection condition among node devices participating in a network, the network configuration management method comprising:
- receiving a request to search for a route from a first node device in the network to a second node device;
calculating route information indicating a route between the first node device and the second node device based on the network configuration information in response to the request to search for a route, calculating route information indicating a route between the first node device and the second node device based on the network configuration information; and
notifying the route information calculated at the calculation step to a request source.
- receiving a request to search for a route from a first node device in the network to a second node device;
-
12. A node device constituting a network together with other node devices, the node device comprising notification means for notifying node-to-node connection information, information about links with adjacent node devices, to a management node device for managing the network as necessary.
-
18. A network configuration management system comprising node devices constituting a network together with other node devices and a management node device for managing the network constituted by the node devices, wherein:
-
each of the node devices constituting the network notifies node-to-node connection information, information about links with adjacent nodes, to the management node device as necessary;
the management node device, in response to receiving a request to connect to the network from a different node device, selects an optimum connection target for the node device; and
a node device which newly connects to the network is connected to the network by connecting to the connection target selected and specified by the management node device.

-
19. A method for controlling node devices constituting a network together with other node devices, the method comprising notifying node-to-node connection information, information about links with adjacent node devices, to a management node device for managing the network as necessary.
-
20. A method for controlling a management node device for managing a network constituted by node devices, the method comprising selecting, in response to receiving a request to connect to the network from a different node device, an optimum connection target for the node device and a notification step of notifying the selected connection target to the different node device.
