METHOD AND APPARATUS FOR DETECTING TOPOLOGY OF NODES AND BRIDGES COMPRISING NETWORK

摘要

PROBLEM TO BE SOLVED: To provide a method and apparatus for detecting a topology of nodes and bridges that comprise a network. SOLUTION: The method for detecting the topology of nodes and bridges that comprise the 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 connected to the same 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.
