Method and system for monitoring and training ethernet channels to support energy efficient ethernet networks

摘要

An Ethernet link may comprise a plurality of active and/or silent channels. Training of one or more link partners for one or more silent channels may be triggered based on monitoring training parameters for an active channel. The link partners may be trained for the silent channels and link partners corresponding to the silent channels may be configured according to the training. Training parameters for an active channel may be compared to a threshold or relative change value. The threshold or relative change value may be fixed, may be based on measurement results and/or may be programmable. The link partners may be configured for silent channels for an echo canceller, a far-end crosstalk canceller and/or a near-end crosstalk canceller. The silent channels may be trained based on transmitting a pulse or LDPC frame via the silent channels.
