    摘要： A network relay device includes a packet buffer for temporarily storing a received packet, and a packet buffer control section for changing an effective buffer number depending on the received amount of packet. When a traffic amount is small, the packet buffer control section reduces the power consumption by stopping the feeding of power or the supply of clock to a part of the packet buffers. The network relay device further includes plural table memories storing a table for deciding the transfer destination of packet, and a table memory control section for changing an effective table number according to a required number of table entries. When the required table entry number is small, the table memory control section reduces the power consumption by stopping the feeding of power or the supply of clock to a part of the table memories.

    摘要： In a client terminal of a communication system, a cipher session establishing section establishes a cipher session use connection between the client terminal as a source client terminal and a relay server by transmitting/receiving a cipher session establishment message between the source client terminal and the relay server, and notifies header information contained in a cipher session header to the relay server. A shared key managing section holds a client shared key with a destination client terminal, A data enciphering section performs encipherment of a data and/or MAC (Message Authentication Code) calculation of the data by using the client shared key and to output the performing result as a client cipher data. A message producing section produces a data communication message including a cipher data field in which the client cipher data is inserted and a non-cipher data field in which the cipher session header containing the header information is inserted. A transmitting section transmits the data communication messages destined to the destination client terminal to the relay server by using the cipher session use connection.

    摘要： 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.
