Abstract
A bridge apparatus for interconnecting networks in which at least two networks including a plurality of stations are connected, and which, when a transmission frame including an identifier of one station and an identifier of another station of a destination is received from the one station, forwards the transmission frame to a network to which the another station belongs based on the identifier of another station. A processor of the bridge apparatus for interconnecting networks performs delivery control of the transmission frame using an information which has been read out of an address check circuit for identifying the network to which the another station belongs with the identifier of the another station which is included in the transmission frame. The address check circuit comprises at least one hash memory in which hash computation results of respective addresses have been stored at respective address positions, and an address memory for storing a plurality of address informations showing a corresponding relationship between identifiers of respective stations and identifiers of respective networks at respective address positions.
