摘要： Computing process with a computational expression is executed using seed information including at least one of destination information and source information associated with a received packet. It is preferable to select a physical port for transmission of the received packet based on the result of the computation. It is also preferable to select a port group for transmission of the received packet based on the result of the computation. Here, the computational expression is capable of being modified. Meanwhile, the physical port for transmission of the received packet is selected from a plurality of candidate ports among the plurality of physical ports. The port group for transmission of the received packet is selected from among a plurality of port groups including a mutually different candidate port.

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.
