Patent ID: 7809966

Claim:
An information processing apparatus comprising: a communication device that communicates with a client apparatus via a network, and has a first memory; an application system device that implements a previously installed plurality of application functions, and has a second memory; a management device that associates and manages application communication for the application functions implemented by the application system device and a port number for receiving the application communication; a power controller that, if the communication device receives a packet addressed to the information processing apparatus from the client apparatus and the received packet is a request for starting connection between the information processing apparatus and the client apparatus and designates the port number managed by the management device when the application system device is in a low power consumption state, restore the application system device from the low power consumption state to a normal power consumption state, wherein the communication device stores the application communication data in the first memory when the communication device receives the application communication data from the client apparatus during a period from when the power controller instructs restoration of the application system device to the normal power consumption state and to when the restoration of the application system to the normal power consumption state is completed, and the communication device transfers the application communication data stored in the first memory to the second memory of the application system device when the restoration of the application system device to the normal power consumption state is completed.
