Abstract:
1. An information processing apparatus comprising: a first controller configured to perform response processing on received packets in a case where the information apparatus operates in a first power mode; and a second controller configured to perform response processing on received packets in a case where the information processing apparatus operates in a second power mode in which the first controller is incapable of performing the response processing; wherein the second controller notifies to the first controller a return instruction of allowing the information processing apparatus to return to the first power mode in a case where the information processing apparatus operates in the second power mode and receives a predetermined packet to which the second controller is incapable of performing the response processing with the second power mode maintained, the first controller performs return processing of allowing the information processing apparatus to return to the first power mode in a case where the first controller receives the return instruction from the second controller, the first controller notifies to the second controller a completion notification representing completion of the return processing in a case where the return processing is completed, and the second controller performs the response processing on the received packets after the second controller has notified the return instruction to the first controller until the second controller receives the completion notification, wherein the received packets are transferred to both the first controller and the second controller after the second controller has notified the return instruction to the first controller until the second controller receives the completion notification.
