<p>Layer 2 (L2) network subject to monitoring has a host terminal A, a host terminal B, an L2 switch A, an L2 switch B, an L2 switch C, and an L2 switch D. A management terminal is connected to the network via the internet or the like. In such a state, the management terminal acquires node information from each node that forms the L2 network, said node information indicating a neighboring node selected as a relay destination for data by a node among neighboring nodes that are adjacent to said node. Moreover, the management terminal uses the acquired node information for each node and connection information between nodes to extract each route along which data is to be relayed in the L2 network.</p> |
