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.
