    摘要: A system and method for carrier deferral for full duplex energy efficient Ethernet (EEE) physical layer devices (PHYs). A carrier deferral signal can be asserted to a media access control layer to indicate to the media access control (MAC) layer that transmission of data is to be deferred due to a power savings initiative in the physical layer device. In one example, the carrier deferral signal is used when a PHY is awakened by the MAC when the MAC has something to transmit. In another example, the carrier deferral signal is used when a PHY is switching link rates.

    摘要: Aspects of a method and system for duty cycling a network device based on aggregate throughput of the device are provided. In this regard, a limit on aggregate ingress and egress data of a network device during a time interval may be determined. Processing of data by the network device may be duty cycled based on the determination. The device may process data at a first rate during a first portion of the time interval and process data at a second rate during a remaining portion of the time interval. In this regard, portions of the device may be slowed or powered down during the first portion of the time interval. Power consumed by the device during the first portion of the time interval may be less than power consumed by the device during the remaining portion of the time interval.

    摘要: In an Ethernet network comprising link partners that are coupled via an Ethernet link, an energy efficient network (EEN) communication control policy may be established above a MAC layer. The EEN control policy may determine a power level mode of operation for the link partners. Power level mode control data may be communicated from hardware, software and/or firmware of upper layer protocols to PHY devices. The control data may specify when, where and/or how long to implement the power level mode. The control data may be communicated via a “magic” packet comprising start and/or end of frame delimiters and bits that indicate the power level mode. The PHY devices may detect, parse and/or interpret the “magic” packet and may enter and/or exit a lower power mode of operation. The PHY devices may respond to by generating a magic packet to upper layers.

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: 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: Aspects of a method and system for controlling a clock frequency in a network device based on aggregate throughput of the device are provided. In this regard, for a network device comprising one or more network ports, a limit on aggregate throughput of the device during a time interval may be determined and an operating frequency of a clock within the network device may be controlled based on the determined limit on aggregate throughput. The limit on aggregate throughput may be determined based on past, present, and/or expected traffic patterns; how many of the device's network ports are active during the time interval, a data rate at which each of the active network ports operates during the time interval; a type of data communicated via the network ports; and/or one or more applications running on the network device during the time interval.
