    摘要: In a conventional “distributed” integrated network node architecture, specific judgment processes cannot be executed in any routing and transferring unit. The routing and transferring unit is required to share judgment process related information with an enhanced processing unit or other routing and transferring units. Thus, when using enhanced processing units, manufacturing costs increase, while processing speed decreases when routing and transferring units cooperate. If any flow is disposed during a transfer from a packet transferring unit in a routing and transferring unit to a processing unit, the packet is disposed regardless of packet priority. In the present invention, a packet related to a specific judgment process is always transmitted to a specific routing and transferring unit from a line interface unit. If an inputted flow is over the transferring capacity, the line interface unit analyzes the packet header and determines the type, transport priority, and disposal priority of the packet.

    摘要: A network switching device includes multiple ports, multiple switching processors, and a table manager. The switching processors respectively have an address table, a output port specification module, an update requirement determination module, and a table update module. The output port specification module refers to a destination address in received data and the address table and specifies a output port for sending the data among the multiple ports. The update requirement determination module determines requirement for update of the address table with regard to a source address in the data. The table manager has an update detail acquisition module and an update request module. Upon determination of the requirement for update of the address table, the update detail acquisition module obtains an update detail of the address table from one of the switching processors. The update request module sends an update request to the switching processors, based on the update detail.

    摘要: A power-saving packet forwarding device realizing electric power that accords to the number of lines in which communication is performed and a traffic volume inputted from the lines. A header processing unit with which the packet forwarding device is equipped has a plurality of packet processing circuits for performing a packet processing. A line number decision circuit monitors the number of lines in which communication is performed and a traffic volume inputted from the line, and decides presence or absence of an operation of a packet processing circuit. Based on this decision result, a power supply and a clock of the packet processing circuit that does not need to operate are interrupted, and accordingly power saving of the packet forwarding device is realized.
