Abstract

A network controller includes a communication portion, a disconnection portion, a change portion, and a re-linking portion. The communication portion is capable of communicating with another network device via a network. The disconnection portion temporarily disconnects communication from the communication portion to the other network device when a sleep signal instructing a shift from a normal state to a sleep state is received. The change portion changes a speed of the disconnected communication from the communication portion to the other network device, to a communication speed lower than a communication speed in the normal state. The re-linking portion causes the communication portion to communicate with the other network device at the changed communication speed.

Description

technical field [0001] The invention relates to a network control device and a network control method. Specifically, it relates to a network control device and a network control method capable of saving power by reducing the communication speed in a sleep state. Background technique [0002] In recent years, when information and data are transmitted / received between a computer and other devices via a network, a network card (hereinafter referred to as NIC) is used as means for connecting the computer and other devices to the network. [0003] The NIC is installed in an expansion slot (bus) of a computer, a workstation, etc. existing on a network, that is, a LAN. After the LAN cable is connected to the NIC, the NIC is controlled by the driver to transfer data. [0004] As a technology of the NIC, for example, there is a media access control device, and Ethernet (registered trademark) of any standard among 10BASE-T, 100BASE-T, and 10BASE-2 can be used with a single media acc...
