Method And System For Simplex Or Duplex Transmission Mode Of An Ethernet Link In An Energy Efficient Network

Abstract

Ethernet link partners within an Ethernet network, coupled via an Ethernet link comprising one or more channels may be configured to operate in simplex mode based on determined condition(s) during communications via the one or more channels. The determined condition(s) may comprise utilization or load, current/past conditions and/or link statistics that may comprise one or more of packet error rate (PER), bit error rate (BER), and/or signal to noise ration (SNR). In addition, one or more of the channels may be transitioned to a lower power mode with a zero data rate. In some embodiments of the invention, one or more of a plurality of operational changes may occur during simplex mode operation. For example, power may lowered for one or more components that enable communication such as receivers, transmitters, near-end cross talk cancellers, far-end cross talk cancellers and/or echo cancellers.
