Abstract:
The object is to realize reasonable power-saving operation in a NIC portion depending on a link status for the Ethernet in a system device including a NIC. For the protocol process functional portion and/or the encryption process functional portion in the NIC portions, the energy-saving process is executed in accordance with conditions, determined whether a protocol process is performed by the NIC or the controller depending on a link status. The power supply to the protocol process functional portion and the encryption process functional portion is turned off in the NIC.
