The energy-efficient operation for Ethernet links standardized by IEEE consists of a low-power state and transition mechanisms between the active state with high power consumption and the low-power state. Reviriego et al. Reported 90% power save in state L where there is no traffic. IEEE, however, did not standardize the triggering mechanism on which conditions state L should be reached. As a result, many algorithms have been proposed for better L state usage, like frame transmission and burst transmission algorithm. |
