Abstract: A network has communication apparatuses communicatively interconnected in compliance with a maintenance protocol. An LBM frame transmission unit transmits an LBM frame to the network. An MEP information acquisition unit identifies a communication apparatus having transmitted an LBR frame as an MEP when the LBR frame is received, and acquires MEP information from the LBR frame. An LTM frame transmission unit transmits an LTM frame to the MEP identified by the MEP information acquisition unit. An MIP information acquisition unit identifies a communication apparatus as an MIP from an LTR frame when the LTR frame is received as a response to the LTM frame, and acquires MIP information indicating information about the MIP. A topology information generation unit generates topology information representing a configuration of the network from the MEP information acquired by the MEP information acquisition unit and the MIP information acquired by the MIP information acquisition unit.

Abstract: A bridge communication system connects a plurality of bridge apparatuses, each connected to a local area network, through a backbone network. The present system performs a node address setting in the bridge apparatuses to add an address of the source node of the backbone network to a data frame. A learning table is provided in the respective bridge apparatuses for storing at least the source address corresponding to the terminal address, the port numbers of each bridge apparatus, and the address of the node of the backbone network. The system searches the learning table using a destination address designating a destination terminal in the data frame transmitted to the respective bridge apparatuses adds an address of a backbone node, obtained by the searching, to the data frame to be transmitted to the backbone network.
