METHOD FOR ACHIEVING LOW POWER CONSUMPTION OF DATA EXCHANGE EQUIPMENT AND APPARATUS THEREOF, AND DATA EXCHANGE EQUIPMENT

摘要

Embodiments of the present invention provide a method and an apparatus for implementing low power consumption for data switching device. The method includes: when identifying that a current state parameter of the device satisfies a preset dormancy configuration parameter, controlling an upper layer logic component in the device to enter a low power consumption state; and when detecting, by using a physical port, that an energy consumption state of a transmission medium is active, waking up the upper layer logic component in the device to enter a normal working state. According to the embodiments of the present invention, the upper layer logic component in the device may be controlled to automatically enter the low power consumption state by automatically detecting the current state parameter of the device; and the energy consumption state of the transmission medium of the physical port is automatically detected and used as external wake-up information to enable the upper layer logic component to automatically enter the normal working state. When a preset condition is satisfied, upper layer logic components such as a CPU, a network processor and an optical module in the device, properly stop full-time operation to save energy.
