Abstract:
1. A network interface apparatus comprising: a first communication control unit arranged to communicate with a network device via a network; a second communication control unit connected to the first communication control unit for communication therewith, the second communication control unit being configured to have a first power status and a second power status that has a lower power consumption than the first power status; the second communication control unit including: an accepting unit arranged to accept received data that has been received by the first communication control unit from the network device when in the first power status; an analyzing/generation unit arranged to analyze the received data accepted by the accepting unit and generate response data in response to the received data; a history information generation unit arranged to generate response history information by associating the received data with the response data corresponding to the received data; and an output unit arranged to output the response history information generated by the history information generation unit to the first communication control unit; the first communication control unit including: a receiving unit arranged to receive data via the network from the network device; a deciding unit arranged to determine a power status of the second communication control unit; a first storing unit arranged to store the response history information outputted by the output unit; a determining unit arranged to determine whether the received data has been registered in the response history information stored in the first storing unit when the received data is received by the receiving unit and the deciding unit determines that the second communication control unit is in the second power status; and a transmitting unit arranged to transmit the response data registered in the response history information in association with the received data when the determining unit determines that the received data has been registered in the response history information.
