Abstract
Includes receiving, from a link partner, a message specifying a link partner receive wake time and resolving to the lesser of the received link partner receive wake time and a local transmit wake time.
Claims58
A method, comprising:
- receiving, from a link partner, a first message including a first receive wake time requested by the link partner;
- determining a first transmit wake time based on the first receive wake time requested by the link partner in the first message and a local transmit wake time;
- after a determination to resume data transmission to the link partner after a temporary halt, delaying transmission of data destined for the link partner based on the determined transmit wake time;
- resuming transmission of data to the link partner, and
- determining a second transmit wake time based on a second, different receive wake time value in a second message received after the first message;
- wherein the first message comprises an LLDP (Link Layer Discovery Protocol) message including the first receive wake time of the link partner and wherein the first receive wake time consists of a 2-octet field value.

A device, comprising:
- at least one Ethernet MAC (media access controller);
- logic constructed to, when in operation:
- receive a message specifying a first receive wake time of a link partner;
- determine a first transmit wake time based on the first receive wake time of the link partner and a local transmit wake time;
- after a determination to resume data transmission to the link partner after a temporary halt, delay transmission of data to the first link partner based on the determined first transmit wake time;
- and
- resume transmission of data;
- wherein the message comprises an LLDP (Link Layer Discovery Protocol) message including the first receive wake time of the link partner and wherein the first receive wake time consists of a 2-octet field value;
- and
- wherein the logic comprises logic constructed to, when in operation, determine a second transmit wake time based on a second, different receive wake time value received after the first receive wake time.
