    摘要: 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.

    摘要: An Ethernet network may comprise multi-rate link partners that may be coupled via an Ethernet link. The Ethernet link may comprise a plurality of channels wherein one or more may be silent and/or idle channels set to a low(er) power that may enable energy efficiency. Silent channels may be utilized for transmitting signals comprising one or more distinct physical patterns for controlling data rate transitions. For example, symbols may be utilized for generating the distinct physical patterns. The distinct physical patterns may communicate a new data rate, when to transition the data rate, which channel(s) may bear the data rate transition and/or a method for implementing the data rate transition. The method may comprise activating or suspending a data traffic channel, modifying a signal constellation, modifying PAM levels and/or adjusting inter-frame gap. The new data rate may be determined based on past traffic and/or expected traffic on the network link.

    摘要: 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 canceller, a near-end crosstalk canceller and a far-end canceller.

    摘要: Aspects of a method and system for a distinct physical pattern on an active channel to indicate a data rate transition for energy efficient Ethernet. In this regard, one or more distinct physical patterns may be transmitted on one or more active channels of a network link during an inter-packet gap to control a data rate on the link. The unique physical pattern may be transmitted instead of or in addition to one or more IDLE symbols. The distinct physical pattern may communicate a data rate to be utilized on the link and/or indicate when a data rate transition should occur on the link. The distinct pattern may be transmitted and/or the data rate transition may occur during a specified inter-packet gap or during a specified packet boundary. The distinct physical pattern may comprise one or more control characters and/or an ordered set of voltage levels, symbols, and/or characters.

    摘要: Aspects of a method and system for managing an energy efficient network utilizing Audio Video Bridging are provided. In this regard, an Audio Video Bridging timeslot may be designated for handling an energy efficient networking (EEN) transaction and the EEN transaction may be performed during the designated timeslot. Exemplary EEN transactions comprise scheduling a data rate transition, transitioning to a different data rate, training a link partner, and exchanging training related information. It may be determined whether the timeslot may be reserved for conveying an AVB stream prior to designating the time slot for an EEN transaction. In instances that the timeslot may be unreserved, the timeslot may be reserved for EEN transaction(s). Information exchanged during the designated timeslot may enable scheduling a data rate transition and/or training on a network link. In this regard, a subsequent timeslot may be designated for the data rate transition and/or the training.
