System and method for energy savings through emulation of wake on lan in energy efficient ethernet

摘要

A system and method for energy savings through emulation of wake on LAN (WoL) in energy efficient Ethernet networks. An intermediary device between a computing device and a network can be alerted that the computing device has entered an energy saving state with wake on LAN (WoL) enabled. The intermediary device can transition the client interface that supports the computing device into an energy saving state and emulate the WoL function of the computing device by listening for a WoL message destined for the computing device. Upon receipt of a WoL message destined for the computing device, the intermediary device can transition the client interface back to an active state then transmit the received WoL message to the computing device.
