1. An energy efficient device, comprising:
- one or more circuits for use in the energy efficient device, said one or more circuits being configured to;
receive, from a power saving device via an electronic communication, information relating to a power saving event in said power saving device;
determine, based on said received information, one or more aggregate power saving statistics from a plurality of power saving events occurring in a measurement interval; and
adjust, based on said determined one or more aggregate power saving statistics, a control policy that determines when said power saving device should enter or exit a power saving state.

Abstract
A system and method for adjusting an energy efficient Ethernet (EEE) control policy using measured power savings. An EEE-enabled device can be designed to report EEE event data. This reported EEE event data can be used to quantify the actual EEE benefits of the EEE-enabled device, debug the EEE-enabled device, and adjust the EEE control policy.

8. An energy efficient device, comprising:
-
a power saving module having circuitry that supports a first and a second state of operation, wherein said first state of operation is an active state that enables communication with a link partner at a first link transmission rate and said second state of operation is a power saving state that enables communication with a link partner at a second link transmission rate lower than said first link transmission rate; a first counter that tracks a number of times said power saving module enters into said power saving state during a measurement interval; a second counter that tracks an amount of time said power saving module is in said power saving state during said measurement interval; and a statistics module that receives results from said first counter and said second counter, said received results enabling said statistics module to track a power saving performance of said power saving module during said measurement interval. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
