Abstract:
1. A switching apparatus having a plurality of ports, comprising: switch information storage to store output port identifiers, which have different directions, and output virtual path identifiers for a combination of an input port identifier, a destination address and an input virtual identifier identifying a virtual LAN, the switch information storage including a detector to detect a first input virtual path identifier and a first destination address assigned to an input packet; a searcher to search the switch information storage for a first output port identifier and a first output virtual path identifier based on a first input port identifier that identifies a port to which the input packet has been input, the first input virtual path identifier, and the first destination address; a packet switch to transfer the input packet to a port identified by the first output port identifier; and a rewriter to rewrite the input virtual path identifier assigned to the input packet into the output virtual path identifier.
