Method And System For Dynamically Determining When To Train Ethernet Link Partners To Support Energy Efficient Ethernet Networks

Abstract

Training, refreshing and / or updating Ethernet link partners for silent channels and / or silent directions of channels may be determined based on control parameters. This may be used to improve energy efficiency in Ethernet communication. Control parameters may comprise a default value and / or may be determined based on prior training, refreshing and / or updating. New values for the control parameters may be generated based on a magnitude of change between current and prior control parameter values or based on performance such as bit error rate. User input may be utilized to determine when to execute the training, refreshing and / or updating. The training, refreshing and / or updating may be done for one or more of a near-end crosstalk canceller, alien near-end crosstalk canceller, far-end crosstalk canceller, alien far-end crosstalk canceller and echo canceller. After the training, refreshing and / or updating, the silent channels may transition to active and / or may remain silent.
