An information processing apparatus determines, upon receipt of a packet via a network while in one of a plurality of power-saving modes, whether the packet is a reply request packet not requiring a process to be performed by the information processing apparatus. When the received packet is a reply request packet not requiring a process to be performed, the information processing apparatus generates a response packet to the received packet while in the one of the powersaving modes. The information processing apparatus returns the response packet via the network to the source of the reply request packet.
