method and device for detection of network architecture

摘要

A method and apparatus for detecting a topology of nodes (211, 212, 213, 214) and bridges (111, 112) that comprise a network, includes the steps of transmitting a message requesting mode switching to the nodes which constitute the network; transmitting check messages to the nodes; receiving reception node information from the nodes, which results from reception of the check messages by the nodes; calculating information about connection of nodes to each line from the reception node information; and extracting information about the topology of bridges and nodes based on the connection information and the reception node information.
