| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a variable-length packet exchange and exchange method by which the band control and transmission priority control of a packet flow are attained. SOLUTION: Each output port interface of a packet exchange includes: a transmission priority controller that classifies a transmission packet received from a packet exchange unit into queue groups by a prescribed algorithm and conducts queuing depending on transmission priority in each queue group; and a packet read controller that reads a transmission packet from each of the queue groups according to the transmission priority while warranting a band assigned to each queue group.
