Abstract

Ethernet link partners within an Ethernet network, coupled via an Ethernet link comprising one or more channels may be configured to operate in simplex mode based on determined condition(s) during communications via the one or more channels. The determined condition(s) may comprise utilization or load, current/past conditions and/or link statistics that may comprise one or more of packet error rate (PER), bit error rate (BER), and/or signal to noise ratio (SNR). In addition, one or more of the channels may be transitioned to a lower power mode with a zero data rate. In some embodiments of the invention, one or more of a plurality of operational changes may occur during simplex mode operation. For example, power may lowered for one or more components that enable communication such as receivers, transmitters, near-end cross talk cancellers, far-end cross talk cancellers and/or echo cancellers.

Claims (35)

1. A method for networking, the method comprising:

in an Ethernet network comprising link partners coupled via an Ethernet link, wherein said Ethernet link comprises a plurality of channels,

determining one or more conditions on said Ethernet link for one or more of said plurality of channels; and

configuring said link partners to operate in a simplex mode on a selected one or selected ones of said plurality of channels when communicating via said Ethernet link, based on said determination.

2. The method according to claim 1 , comprising transitioning said one or more of said plurality of channels to a zero data rate lower power mode.

3. The method according to claim 1 , comprising during said simplex mode operation, lowering power for one or more components that enables communication via said one or more of said plurality of channels.

4. The method according to claim 1 , comprising during said simplex mode operation, lowering power for one or more receivers that enables communication via said one or more of said plurality of channels.

5. The method according to claim 1 , comprising during said simplex mode operation, lowering power mode for one or more transmitters that enables communication via said one or more of said plurality of channels.

6. The method according to claim 1 , comprising during said simplex mode operation, lowering power for one or more near-end cross talk cancellers, one or more far end cross talk cancellers and/or one or more echo cancellers that enables communication via said one or more of said plurality of channels.

7. The method according to claim 1 , wherein said one or more conditions comprise a load on said link partners and/or utilization of said Ethernet link.

8. The method according to claim 1 , wherein said one or more conditions comprise current and/or past link conditions on said Ethernet link.

9. The method according to claim 1 , wherein said one or more conditions comprise link statistics comprising one or more of packet error rate (PER), bit error rate (BER), and/or signal to noise ratio (SNR) of said Ethernet link.

10. A system for networking, the system comprising:

one or more circuits for use in one or more link partners that are coupled via an Ethernet link, said Ethernet link comprising a plurality of channels, said one or more circuits operable to determine one or more conditions on said Ethernet link for one or more of said plurality of channels; and

said one or more circuits operable to configure said link partners to operate in a simplex mode on a selected one or selected ones of said plurality of channels when communicating via said Ethernet link, based on said determination.

11. The system according to claim 10 , wherein said one or more circuits enables transition of said one or more of said plurality of channels to a zero data rate lower power mode.

12. The system according to claim 10 , wherein said one or more circuits enables during said simplex mode operation, lowering of power for one or more components that enables communication via said one or more of said plurality of channels.

13. The system according to claim 10 , wherein said one or more circuits enables during said simplex mode operation, lowering of power for one or more receivers that enables communication via said one or more of said plurality of channels.

14. The system according to claim 10 , wherein said one or more circuits enables during said simplex mode operation, lowering of power mode for one or more transmitters that enables communication via said one or more of said plurality of channels.

15. The system according to claim 10 , wherein said one or more circuits enables during said simplex mode operation, lowering of power for one or more near-end cross talk cancellers, one or more far end cross talk cancellers and/or one or more echo cancellers that enables communication via said one or more of said plurality of channels.

16. The system according to claim 10 , wherein said one or more conditions comprise a load on said link partners and/or utilization of said Ethernet link.

17. The system according to claim 10 , wherein said one or more conditions comprise current and/or past link conditions on said Ethernet link.

18. The system according to claim 10 , wherein said one or more conditions comprise link statistics comprising one or more of packet error rate (PER), bit error rate (BER), and/or signal to noise ratio (SNR) of said Ethernet link.

19. A non-transitory computer readable storage having stored thereon, a computer program having at least one code section for networking, the at least one code section being executable by a machine for causing the machine to perform steps comprising:

in an Ethernet network comprising link partners coupled via an Ethernet link, wherein said Ethernet link comprises a plurality of channels,

determining one or more conditions on said Ethernet link for one or more of said plurality of channels; and

configuring said link partners to operate in a simplex mode on a selected one or selected ones of said plurality of channels when communicating via said Ethernet link, based on said determination.

20. The non-transitory computer readable storage according to claim 19 , wherein said at least one code section comprises code for transitioning said one or more of said plurality of channels to a zero data rate lower power mode.

21. The non-transitory computer readable storage according to claim 19 , wherein said at least one code section comprises code for, during said simplex mode operation, lowering power for one or more components that enables communication via said one or more of said plurality of channels.

22. The non-transitory computer readable storage according to claim 19 , wherein said at least one code section comprises code for, during said simplex mode operation, lowering power for one or more receivers that enables communication via said one or more of said plurality of channels.

23. The non-transitory computer readable storage according to claim 19 , wherein said at least one code section comprises code for, during said simplex mode operation, lowering power mode for one or more transmitters that enables communication via said one or more of said plurality of channels.

24. The non-transitory computer readable storage according to claim 19 , wherein said at least one code section comprises code for, during said simplex mode operation, lowering power for one or more near-end cross talk cancellers, one or more far end cross talk cancellers and/or one or more echo cancellers that enables communication via said one or more of said plurality of channels.

25. The non-transitory computer readable storage according to claim 19 , wherein said one or more conditions comprise a load on said link partners and/or utilization of said Ethernet link.

26. The non-transitory computer readable storage according to claim 19 , wherein said one or more conditions comprise current and/or past link conditions on said Ethernet link.

27. The non-transitory computer readable storage according to claim 19 , wherein said one or more conditions comprise link statistics comprising one or more of packet error rate (PER), bit error rate (BER), and/or signal to noise ratio (SNR) of said Ethernet link.
