Abstract

Systems and methods for implementing an Energy-Efficient Ethernet (EEE) communication are provided. In some aspects, a method includes identifying an EEE signal configured to be communicated via a first set of wires. The method also includes processing the EEE signal such that the processed EEE signal is configured to be communicated via a second set of wires. The second set of wires including fewer wires than the first set of wires. The method also includes communicating the processed EEE signal via the second set of wires.

Claims (36)

1. A method for implementing an Energy-Efficient Ethernet (EEE) communication, the method comprising:

receiving, from a media access control (MAC) layer, a plurality of data streams at an input of a first physical layer of a first electronic device via a first set of wires;

identifying, at the first physical layer, an EEE signal in the plurality of data streams received via the first set of wires, the EEE signal being associated with one of a first EEE signal type or a second EEE signal type;

combining, at the first physical layer, the plurality of data streams into a combined data stream for transmission via a second set of wires, the second set of wires comprising a single twisted pair of wires, the first set of wires comprising more wires than the second set of wires;

encoding, at the first physical layer, the combined data stream to include a first indication of the EEE signal when the EEE signal is associated with the first EEE signal type and encoding the combined data stream to include a second indication of the EEE signal when the EEE signal is associated with the second EEE signal type, the first indication and the second indication identifying different low power idle signals; and

communicating the encoded combined data stream at an output of the first physical layer of the first electronic device via the second set of wires, the encoded combined data stream being communicated in a full-duplex mode from the first physical layer of the first electronic device to a second physical layer of a second electronic device over the single twisted pair of wires.

2. The method of claim 1 , wherein the first set of wires comprises eight wires, and wherein the second set of wires comprises two wires.

3. The method of claim 1 , wherein the second set of wires are unshielded.

4. The method of claim 1 , wherein the EEE signal comprises a plurality of EEE signal portions, and wherein each portion of the plurality of EEE signal portions is received via a respective one of the first set of wires.

5. The method of claim 1 , wherein the EEE signal comprises one or more EEE signal portions, and wherein each portion of the one or more EEE signal portions is received via the second set of wires in a time division manner.

6. The method of claim 1 , further comprising processing the EEE signal, wherein processing the EEE signal comprises at least one of routing, switching, splitting, duplicating, delaying, muxing, encoding, scrambling, modulating, mapping, or modifying the EEE signal.

7. The method of claim 6 , wherein the EEE signal comprises one or more send zero signals, and wherein processing the EEE signal comprises distributing the one or more send zero signals via the second set of wires.

8. The method of claim 1 , wherein receiving the plurality of data streams comprises receiving the EEE signal from a media access control layer of the first electronic device, and wherein the encoded combined data stream comprising the first or second indication is communicated to the second electronic device via the second set of wires.

9. The method of claim 1 , wherein the first indication of the EEE signal comprises at least one of a low power idle signal, a low power idle initiation request, a low power idle acknowledgment, a low power refresh signal, a low power quiet signal, a low power wake signal, a send zero signal, a signal for synchronizing one or more low power states between the first electronic device and the second electronic device, or a signal for changing the one or more low power states.

10. The method of claim 1 , further comprising:

communicating another EEE signal in the full-duplex mode from the second physical layer of the second electronic device to the first physical layer of the first electronic device over the single twisted pair of wires while the encoded combined data stream is being communicated over the single twisted pair of wires.

11. The method of claim 1 , wherein:

the first indication is encoded into the encoded combined data stream based on the EEE signal being encoded with a first portion of a physical coding sublayer (PCS) transmit function, and

the second indication is encoded into the encoded combined data stream based on the EEE signal being encoded with a second portion of the PCS transmit function, the second portion being different than the first portion.

12. A method for implementing an Energy-Efficient Ethernet (EEE) communication, the method comprising:

receiving an encoded data stream communicated to an input of a second physical layer of a second electronic device via a first set of wires, the encoded data stream being communicated in a full-duplex mode between a first physical layer of a first electronic device and the second physical layer of the second electronic device over a single twisted pair of wires of the first set of wires;

decoding, at the second physical layer of the second electronic device, the encoded data stream to identify at least one of a plurality of EEE signal types of an EEE signal encoded into the encoded data stream;

separating, at the second physical layer of the second electronic device, the decoded data stream into a plurality of data streams to communicate the decoded EEE signal via a second set of wires from the second physical layer of the second electronic device, the second set of wires comprising more wires than the first set of wires, the decoded EEE signal identifying a low power idle signal; and

providing the decoded EEE signal and the plurality of data streams to the second set of wires.

13. The method of claim 12 , wherein the first set of wires comprises two wires, and wherein the second set of wires comprises eight wires.

14. The method of claim 12 , wherein the EEE signal comprises one or more EEE signal portions, and wherein each portion of the one or more EEE signal portions is received via a respective one of the first set of wires in a time division manner.

15. The method of claim 12 , wherein the EEE signal comprises a plurality of EEE signal portions, and wherein each portion of the plurality of EEE signal portions is transmitted via a respective one of the second set of wires.

16. The method of claim 12 , further comprising processing the EEE signal, wherein processing the EEE signal comprises at least one of routing, switching, splitting, duplicating, delaying, demuxing, descrambling, demodulating, demapping, or modifying the EEE signal.

17. The method of claim 12 , wherein the EEE signal is received from the first electronic device via the first set of wires, and wherein the decoded EEE signal is provided to a media access control layer of the second electronic device via the second set of wires.

18. A system comprising:

at least one processor circuit configured to:

identify an EEE signal in a plurality of data streams communicated via a first set of wires to a first physical layer of a first electronic device, the EEE signal being associated with one of a plurality of EEE signal types;
