Abstract:
1. A system device comprising a NIC including a network I/F, a protocol process functional portion, and an encryption process functional portion as well as a controller responsible for overall control to provide various network services to external devices connected to a network, the controller performing, based on a condition determined depending on a service request status, power-saving control that selectively reduces or terminates processing abilities of the protocol process functional portion and/or the encryption process functional portion by applying to the protocol process functional portion and/or the encryption process functional portion of the NIC a combination of different energy-saving processes corresponding to the processing functions thereof to stepwise reduce electric power consumed by constituent elements of the process functional portions in accordance with the condition, wherein the controller creates a network service provision list including at least record items that are information of time when service requests are made, identification information of nodes making service requests, types of requested services, and a weighting value of each type of services to determine the condition from the total value of the weighting values within a predetermined period.
