The present invention relates to a method of operating a crossbar switch (1) having a control logic (2) and n input ports (i-0, . . . , i_n-1) and m output ports (o-0, . . . , o_m-1), wherein information packets of p different priority levels are routed from said n input ports (i-0, . . . , i_n-1) to said m output ports (o-0, . . . , o_m-1). Within said control logic (2), a pool (CRA) of buffers (CRA-0, CRA-1, . . . ) is provided for each crosspoint (4) for temporarily storing address information related to said information packets.
