Abstract
The invention relates to a switching device which transports data packets from input ports to selected output ports. The payload of the packets is stored in a storage means. A switching means is arranged which has more switch outputs than switch inputs and which switches sequentially between one switch input and several switch outputs while storing the payloads. Furthermore, the invention relates to a storing method which uses switching means to store payloads in a sequential order and to a switching apparatus comprising several switching devices. Furthermore, the invention relates to systems using the switching device as a scaleable module.
