The invention relates to a packet switching device comprising a plurality of line cards (1 and 2), each consisting of a port control system (6 and 7) for storing and arranging packets in output queues and for the clocked generation and amendment of weightings containing information about the states of the output queues, and comprising a plurality of switch cards (3 to 5), each consisting of a crosspoint matrix (8) and an arbiter (9) for controlling the crosspoint matrix (8). Herein, the port control systems (6 and 7) each transmit to the arbiter (9) an amended weighting selected from a Table using a round robin method (30).
