Abstract: An Ethernet link may comprise silent and active channels and may support energy efficient Ethernet communication. Training parameters from the one or more active channels may be utilized for determining and/or adjusting training parameters for silent channels prior to activation. Training parameters for silent channels may be determined based on copying training parameters from active channels. Determination of training parameters for silent channels may be based on a weighted average of the active channel training parameters. A delta between active channel training parameters from a prior time and subsequent time may be utilized to determine a correction factor for adjusting training parameters for a silent channel from a prior time. Silent channels may be adjusted based on active channel training parameters and then subsequently may be trained. Training parameters may be adjusted for one or more of an echo canceler, a near-end crosstalk canceler and a far-end canceler.

Abstract: Aspects of a method and system for compensated time stamping for time-sensitive network communications are provided. In this regard, one or more timestamps generated in an OSI layer above the physical layer may be adjusted based on parameters associated with an amount of time in which data traverses a PHY of the network device. Communications of the network device may be managed based on the adjusted one or more timestamps. The parameters may comprise one or more of: average ingress PHY traversal time, average egress PHY traversal time, variance of ingress PHY traversal time, and variance of egress PHY traversal time. One or more network links coupled to the network device may be characterized based on the one or more adjusted timestamps. The parameters may be stored in one or more registers within a PHY of the network device.

Abstract: Aspects of a method and system for supporting a variable and energy efficient data rate using a duty cycling technique and multiple power states on an Ethernet link are provided. In this regard, a data rate on a network link may be duty cycled based on characteristics of data communicated over it. The network link may operate at a first data rate for a first portion of the time interval and may operate at a second data rate for a second portion of the time interval. The duration of each portion of the time interval and/or the data rate during each portion of the time interval may be adjusted to control the duty cycling. Power consumed in a device connected to the network link may be controlled based on the duty cycling of the link.

Abstract: An Ethernet link may comprise one or more link partners that may be communicatively coupled via one or more silent channels, One or more circuits and/or parameters corresponding to silent channels may be retrained, refreshed and/or updated based on various triggers, for example, fixed times, periodic or aperiodic time intervals, random or pseudorandom timer, events, link statistics, physical conditions such as noise, temperature level, cable type and/or cable length, communication from a corresponding link partner and/or based on programming from, for example, a layer above the physical layer. The retraining, refreshing and/or parameter updating may occur for one or more of an echo canceller, a far-end crosstalk canceller and a near-end crosstalk canceller corresponding to the one or more silent channels. Subsequent to the retraining, refreshing and/or parameter updating, the one or more silent channels may be activated and/or may remain silent.
