Data processing apparatus, information processing method, and storage medium

摘要

A data processing apparatus includes first and second information processing apparatuses. The first information processing apparatus has a first power mode and a second power mode in which electric power consumption is smaller than in the first power mode. The second information processing apparatus is capable of communicating with the first information processing apparatus and an external apparatus via a network. Definition information including identification information identifying a packet received via the network and process information indicating a process to be performed on the packet is received at least from one of the first information processing apparatus and the external apparatus. If a packet is received from the external apparatus in the second power mode, the packet is analyzed to identify definition information corresponding to the packet based on the identification information. A process is performed according to the process information included in the definition information.

主权项

1. A data processing apparatus comprising:
a first control unit configured to control the data processing apparatus; a registration unit configured to register definition information including first identification information and first process information, the first identification information identifying a packet received from an external apparatus via a network, the first process information indicating a process to be performed on the packet; an electric power control unit configured to control supplying of electric power such that electric power is supplied to the first control unit in a normal power mode and supplying of electric power is stopped at least to the first control unit in a power saving mode; and a second control unit configured to, when a packet is received from the external apparatus in the power saving mode, determine the first identification information based on the received packet, and then perform a process according to the first process information corresponding to the determined first identification information, the second control unit being further configured to control registration such that second identification information and second process information are newly registered in the registration unit as a part of the definition information according to an instruction given from the external apparatus if the second identification information is not already registered in the registration unit, the second identification information identifying a packet received from the external apparatus via a network, the second process information indicating a process to be performed on the packet, wherein the second control unit is configured to control registration such that the first process information is updated in the registration unit if the second identification information is already registered in the registration unit as a part of the definition information and the second process information is different than the first process information already registered in the registration unit.
