ABSTRACT:
A packet forwarding apparatus provided with a plurality of line interface units, comprises a routing processing unit for referring to a routing table, based on header information of received packet to specify one of output lines to output the received packet, a flow detection unit for referring to an entry table, in which a plurality of entries with flow conditions and control information are registered, to retrieve control information defined by the entry with a flow condition which coincides with that of the header information of the received packet, and a packet forwarding unit for transferring the received packet to one of the line interface units connected to the output line specified by the routing processing unit. The entry table id divided into a plurality of subtables corresponding to the values of flow attributes associated with the received packets and the flow detection unit retrieves the control information from one of said subtables specified by the value of the flow attribute corresponding to the received packet.
