Energy efficient ethernet with asymmetric low power idle

摘要

Energy efficient Ethernet with asymmetric low power idle. Low power idle mode is typically leveraged when both direction of a link do not have data traffic to transmit. Such a requirement reduces the application of low power idle due to the frequent existence of data traffic in only one direction. An asymmetric low power idle mode enables reduction in power consumption and signal emissions even when one direction has data traffic to transmit.
