Abstract
An Ethernet communication device includes a data interface and circuitry. The data interface is configured for communicating with a neighbor device. The circuitry is configured to exchange Ethernet data frames with the neighbor device over the data interface, wherein successive data frames are separated in time by an Inter-Packet Gap (IPG) having at least a predefined minimal duration, and to further exchange with the neighbor device, over the data interface, during the IPG between Ethernet frames exchanged on the data interface, a wake-up/sleep command that instructs switching between an active mode and a sleep mode.
