Sleep signaling handshake for ethernet
By delaying the transmission of LPS requests to silence the transmitter until the link partner has finished processing or the timer expires, the contention during sleep mode transitions of communication devices is resolved, resulting in more efficient power savings and link stability.

AI Technical Summary
Technical Problem
In existing technologies, communication devices are prone to contention when switching to sleep modes, leading to unnecessary power consumption and communication link failures.
Method used
By delaying the sending of LPS requests to silence the transmitter until the link partner has finished processing the LPS request or the timer expires, the integrity of the handshake process is ensured, and unnecessary transmitter silence is avoided.
Benefits of technology
It significantly reduces power consumption caused by competition during sleep mode transitions in communication devices, thereby improving the stability and efficiency of the communication link.

Abstract
Embodiments of this disclosure relate to a sleep signaling handshake in Ethernet. A first communication device performs a handshake process with a second communication device, the handshake process being associated with a transition from an active mode to a low-power mode. i) After the handshake process is completed, and ii) at least until a) the expiration of a time period and b) the earlier of determining that the second communication device has silenced its transmitter, the first communication device sends data and / or idle symbols to the second communication device. The first communication device transitions to a low-power mode in conjunction with the handshake process.
