ABSTRACT:
Aspects of a method and system for low power IDLE signal transmission in Ethernet networks are provided. In this regard, during time periods between transmissions of actual data by a local Ethernet link partner, the local Ethernet Link partner may generate one or more signals, in place of a standard Ethernet IDLE signal, that enable synchronization between Ethernet link partners. In this manner, the generated signals may enable reducing power consumption as compared to standard Ethernet IDLE signals. Accordingly, link activity may be monitored to enable detecting periods when there may be no actual data for transmission and the generated signals may be transmitted. The generated signals may be transmitted at a reduced symbol rate as compared to standard Ethernet IDLE signals. The generated signals may be transmitted via fewer network links as compared to standard Ethernet IDLE signals.
