Information processing device and method of controlling information processing device

A method of controlling an information processing device that includes a network interface and a controller and is operable in a plurality of power modes including a first power mode and a second power mode in which power consumption is less than power consumption of the first power mode, the method comprising:

• receiving, by the controller, a packet via the network interface and performing control such that a process corresponding to the received packet is performed when the information processing device operates in the first power mode;
• performing control, by the network interface, such that a process of transmitting the received packet to the controller is performed when the information processing device operates in the first power mode;
• and
• performing control, by the network interface, such that a process of discarding the received packet or the process of transmitting the received packet to the controller is performed when the information processing device operates in the second power mode,
• wherein the network interface has a storage area in which a discarding determination pattern which is information used to determine whether the received packet is discarded or transmitted to the controller is stored, and
• wherein the controller performs control such that a process of updating a list of the discarding determination pattern to be stored in the network interface is performed based on determination of whether a process on the received packet in the controller is a discarding process,
• wherein the discarding determination pattern is a pattern in which a packet matching the discarding determination pattern is discarded,
• wherein a process of discarding the received packet is performed by the network interface when predetermined packet information stored in the received packet accords with the discarding determination pattern, and
• wherein a new discarding determination pattern is generated based on the received packet and the discarding determination pattern of the storage area of the network interface is updated when the process on the received packet transmitted from the network interface is the discarding process.

An information processing device that is operable in a plurality of power modes including a first power mode and a second power mode in which power consumption is less than power consumption of the first power mode, the information processing device comprising:

• a network interface;
• and
• a controller,
• wherein the controller receives a packet via the network interface and performs a process corresponding to the received packet when the information processing device operates in the first power mode,
• wherein the network interface performs a process of transmitting the received packet to the controller when the information processing device operates in the first power mode, and performs a process of discarding the received packet or the process of transmitting the received packet to the controller when the information processing device operates in the second power mode,
• wherein the network interface has a storage area in which a discarding determination pattern which is information used to determine whether the received packet is discarded or transmitted to the controller is stored,
• wherein the controller performs a process of updating a list of the discarding determination pattern to be stored in the network interface based on determination of whether a process on the received packet in the controller is a discarding process,
• wherein the discarding determination pattern is a pattern in which a packet not matching the discarding determination pattern is discarded,
• wherein the network interface performs a process of discarding the received packet when predetermined packet information stored in the received packet does not accord with the discarding determination pattern, and
• wherein the controller deletes the discarding determination pattern from storage area when the process on the received packet in the controller is a discarding process.
