Abstract
A network device may be provided with a PHY layer process unit, a determination unit configured to determine that a link state is a link up state or a link down state, and a first control unit configured to control an electrical power supply for the PHY layer process unit. The first control unit may be configured to stop a continuous electrical power supply for the PHY layer process unit if the determination unit determines that the link state is the link down state during a first period in which the continuous electrical power supply is being performed, perform a temporary electrical power supply for the PHY layer process unit during a second period, and commence the continuous electrical power supply if the temporary electrical power supply is performed during the second period and the determination unit determines that the link state is the link up state.
