A network linking device in communication with a computer host and an external network is disclosed. The network linking device includes a media access controller (MAC), a buffer and a feature value evaluator. The MAC in communication with the external network receives a data packet from the external network, and stores the data packet in the buffer in communication therewith. The feature value evaluator in communication with the buffer determines whether the data packet complies with a transfer condition according to a feature value included in the data packet, and actuates the MAC to assert an interrupt signal to the computer host when the feature value indicates the data packet complies with the transfer condition. A method for transferring a data packet between a computer host and an external network is also disclosed.

Network linking device and method for transferring data packets by the same

The present invention discloses a method and an apparatus for reducing power consumption in a network linking system. The apparatus comprises: a network linking interface device, including a media access controller (MAC), a gigabit physical layer (gigabit PHY), and a connector, through which the network linking interface device is coupled to an Ethernet by a network cable; a driving device, for driving and controlling the network linking interface device; and a load monitoring module, for monitoring the load for the network interface device so as to adjust the link speed according to the load. The method comprises steps of: determining the network linking interface device to be in an autonegotiation mode; performing autonegotiation; obtaining settings of a remote-end network linking interface device; linking at the highest usable link speed; enabling the load monitoring module; adjusting the settings of the network linking interface device according to the load of the network linking interface device; and performing autonegotiation again and linking at a proper link speed.
