Abstract

The invention relates to a packet switching device with a plurality of input and output ports and at least one switching unit (3 to 5) comprising a coupling matrix and an arbiter unit (9) for controlling the coupling matrix (8), wherein the arbiter unit is designed for generating a state matrix (11) whose lines each correspond to an input port and whose columns each correspond to an output port, said state matrix comprises elements which each represent a weighting for an interconnection between an input port and an output port of the packet switching device, and said arbiter unit (9) is designed for forming a first decision matrix consisting of several accepted interrelationships on the basis of an algorithm which is operative in parallel on several groups (12 and 14) of columns of the state matrix.
