Patent ID: 8214676

Claim:
An information processing apparatus, comprising: a first control unit configured to control a system relevant to the information processing apparatus; a second control unit configured to control a network controller that is connected to a network and that controls a process relevant to packets; a packet table in which at least one packet to be processed by the first control unit is registered, among the packets transmitted/received via the network; and a determining unit configured to determine whether the system can switch to a power saving mode, wherein when the first control unit does not process the packets for at least a certain period of time, the information processing apparatus switches from a regular power mode in which both the first control unit and the second control unit operate at a capacity to process packets, to the power saving mode in which power is not supplied to the first control unit; when the determining unit determines that the system can switch to the power saving mode from the regular power mode, the network controller processes the packets based on the packet table; and the packets are processed based on the packet table in both the regular power mode and the power saving mode.
