Abstract
A system and method for using energy-efficient Ethernet to control energy efficiency in lower layers. In one example, an energy-efficiency control policy in a first Ethernet device can be configured to determine a need for transitioning of at least a part of the first Ethernet device into an energy saving state. Based on such a determination, an energy-efficiency control signal can be transmitted from the first Ethernet device to a first non-Ethernet device. The receipt of the energy-efficiency control signal by the first non-Ethernet device is used to initiate a transition by the first non-Ethernet device into an energy saving state, which in turn may initiate a transition by downstream non-Ethernet devices into an energy saving state. This process creates a single unified energy-efficiency policy domain.
