Abstract
A spanning tree creation unit creates a plurality of spanning trees based on the network topology, and registers the spanning trees to a spanning tree information table. A spanning tree selection unit selects a spanning tree wherein communication resources will be used most effectively, out of the plurality of spanning trees registered to the spanning tree information table. A node setup unit sets the mapping information which expresses correspondence between the requested virtual LAN and the selected spanning tree in each node.
