    摘要: Aspects of a method and system for determining physical layer traversal time are provided. In this regard, duration of a time interval may be determined in the PHY of a network device, where the time interval corresponds to an amount of time that occurs between a first time instant at which information is input to the PHY and a second time instant at which corresponding information is output by the PHY. Communication of data to and/or from the network device may be managed based on the determined duration of the time interval. The duration of the time interval may be determined utilizing one or more counters within the PHY. The determined duration may be stored in one or more registers within the PHY. An amount of data that is processed by the PHY during the time interval may be determined within the PHY.

    摘要: A system and method for energy savings on a PHY/MAC interface for energy efficient Ethernet. Power savings for a PHY due to low-link utilization can also be realized in the higher layer elements that interface with the PHY. In one embodiment, subrating is implemented on a MAC/PHY interface to match a subrating of the PHY with a remote link partner. This subrating is less than the full capacity rate and can be zero.

    摘要: Aspects of a method and system for utilization of a reserved and/or out of band channel for managing a data rate of an Ethernet channel are provided. In this regard, a data rate of a network link may be managed via traffic communicated over a reserved and/or out of band channel on said network link. The reserved and/or out of band channel may be an auxiliary channel established in the IEEE 802.11AN standard. Traffic communicated over the reserved and/or out of band channel may enable negotiating a data rate for the link, scheduling a change in the data rate on the link, exchanging link state information, configuring a number of active physical channels on the link, configuring a signal constellation utilized for representing data on said the link, configuring an inter-frame or inter-packet gap, and/or configuring signal levels utilized for signaling on the 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: Signals may be communicated with A/V Bridging services between an upstream link partner and a down stream link partner, each comprising an asymmetric multi-rate Ethernet physical layer (PHY). High bandwidth A/V signals may be transmitted from the upstream link partner and low bandwidth signals may be transmitted from the downstream link partner. One or more of a time stamp, a traffic class and/or a destination address may be utilized in generating PDUs as well as data rate request and a resource reservation messages via the asymmetric Ethernet PHY. The receiving link partner may register for deliver of the PDUs. An aggregate communication rate may be distributed evenly or unevenly among one or more links for transmission and aggregated upon reception via asymmetric multi-rate Ethernet PHY operations. Compressed, uncompressed, encrypted and/or unencrypted signals may be handled. Signal processing may comprise echo cancellation, cross talk cancellation, forward error checking and equalization.

    摘要: Aspects of a method and system for symmetric transmit and receive latencies in an energy efficient PHY are provided. In this regard, a delay introduced by a PHY of a network device for outbound traffic and a delay introduced by the PHY for inbound traffic may be controlled such that a transmit delay of the network device is equal, within a tolerance, to a receive latency of the network device. The delays may be controlled based on whether one or more energy efficiency features are enabled in the PHY. The delay introduced by the PHY for outbound traffic may be controlled based on an amount of buffered inbound traffic. The delay introduced by the PHY for inbound traffic may be controlled based on an amount of buffered outbound traffic. The delays may be controlled such that said receive latency and the transmit latency are approximately constant regardless of a mode of operation of the network device.
