A multi-protocol switching system of the invention has a plurality of line interfaces that has an input section for inputting data from a network, a forwarding table, a determination section for determining a destination or the input data, a packet generating section for generating a packet, when the destination determined is a protocol processor, by adding a processor identifier of the protocol processor and a port number to which the multi-protocol processing device is connected to the input data, and an output section for outputting the packet through the port to a switch. Also it has one or more multi-protocol processing devices that has a switch interface, a plurality of protocol processors which are provided corresponding to the kind of protocol and each of which has a processor identifier defined in the multi-protocol processing device, and a processor selecting section.
