Abstract
A method of reducing Ethernet power consumption in a network having an operating system by reducing an Ethernet link speed to a minimum rate required for current data link traffic, and automatically commanding an Ethernet adapter/cable to decrease or increase a link rate by dynamically auto-negotiating an Ethernet port by IEEE standards to a lower or higher link rate without user intervention.
