Document Type and Number:

Japanese Patent JP2003209568

Kind Code:

A

Abstract:

To select a path reflecting a link use situation by linking traffic information on a current link to a link state type routing protocol.

A node is provided with a traffic observing part, traffic information obtained by observation is attached to link state information, and the traffic information is reflected to select a path. To reflect the traffic information on the link state information, a method for publicly announcing the link state information is used to update a link state DB by flooding. Otherwise, the traffic information of each node is transmitted to a traffic information collection and distribution device that collectively manages traffic information, and the traffic information collection and distribution device collects the traffic information from the respective nodes and distributes the traffic information to the respective nodes. The respective nodes update the link state DB from the distributed traffic information.
