Abstract
Network devices coupled via serial and/or parallel interfaces may determine a power level mode of operation according to an energy efficient network communication control policy and may configure one or more of the interfaces for the lower power mode. The network devices may comprise a PHY, a MAC and/or higher layer devices. The interfaces may comprise a XGMII extender, a XAUI and/or a XFI device. The interfaces may comprise a backplane PHY, for example, a 10GBASE-KR, a 10GBASE-KX4 and/or a 1GBASE-KX PHY which may perform FEC. The interfaces may comprise direct attach copper such as SFP+ and/or InfiniBand and/or 10GBASE-CX4 PHYs. The interfaces may comprise a pluggable transceiver module. Energy efficient network control data may be communicated to and/or from the network devices which may enter and/or exit a lower power mode of operation.
