Apparatus and method for shortening time for transitioning power mode of network communication device by utilizing a shared storage unit, a socket, and a socket wrapper

摘要

A network communication device includes a first control unit that has a first application, a second control unit that has a second application and a communication processing section, and a shared storage unit, wherein, in a first mode where the first control unit is in an operation state, the first application performs a predetermined process using the shared storage unit, and the communication processing section performs communication in response to an instruction from the first application, and wherein, if the first control unit transitions from the first mode to a second mode in which power consumption is lower than that in the first mode, the first application stops execution of the process, the second application performs a process based on data related to the first application, stored in the shared storage unit, and the communication processing section performs communication in response to an instruction from the second application.

1. A network communication device comprising:
a first control unit that has a first application section; a second control unit that has a second application section and a communication processing section performing a communication process via a communication network; and a shared storage unit that can be used by the first control unit and the second control unit, wherein, in a first mode where the first control unit is in an operation state, the first application section performs a predetermined process using the shared storage unit, and the communication processing section performs communication in response to an instruction from the first application section, wherein, if the first control unit transitions from the first mode to a second mode in which power consumption is lower than that in the first mode, the first application section stops execution of the process, the second application section performs a process based on data related to the first application section, stored in the shared storage unit, and the communication processing section performs communication in response to an instruction from the second application section, and wherein the communication processing section includes a socket that is used to transmit a data to an external device and receive a data from an external device by the communication processing section, and wherein the first control unit further includes a socket wrapper that sends data transmitted by the first application section to the socket and sends data received by the socket to the first application section in the first mode.
