Patent Number: 7,788,714

Title: Packet transfer apparatus

Abstract: Plural retrieval units are prepared, and a retrieval unit which can reduce power consumption is selected according to the condition of a retrieval key. For example, in general, the retrieval unit including a CAM is used. However, when the condition of the retrieval key is simple as in a case where reference is made to only TOS in an interior node of Diffserv and QoS is determined, the retrieval unit including a dscp-QoS table constituted of an FF or RGF is used and the power consumption is reduced. A CAM retrieval start determination section determines that a process is performed by which retrieval unit in accordance with previously set setting information or a previously set header information item.
