A packet switch has a switching architecture comprising a cross network of input and output switching links crossing each other. The output switching links form a number of tree structures, which each includes an upper buffering level, which includes a number of intermediate storing buffers for packets entering on the input links, and a lower buffering level with at least one output buffer connected for reception of the contents in at least two of the intermediate storing buffers of the upper buffering level, and the output of which forms an output of its respective output switching link.
