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 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.
