In a LAN relaying/switching apparatus which can guarantee data to be transmitted, a predetermined amount of transmission line bandwidth is set to a bandwidth control queue unit for a the data flows with a top priority, a remaining transmission line bandwidth is secured for a priority control queue unit according to the order of priority of the remaining data flows. A controller performs a read processing of the priority control queue unit at a timing different from a timing of reading the bandwidth control queue unit.
