    Abstract: An Ethernet passive optical network over coaxial (EPOC) system rate mechanism. A network device is provided that includes a physical layer device (PHY) that is configured for coupling to a coaxial cable, a medium independent interface that facilitates data transmission at 10 Gbit/s or greater, and a reconciliation sublayer that is coupled to the PHY via the medium independent interface. The reconciliation sublayer has a codeword detector that is configured to detect a reserved codeword that is received from the PHY over the medium independent interface. The codeword detector can be configured to forward a rate control signal to a media access control (MAC) based on the detection of the reserved codeword.

    Abstract: A system and method for using energy-efficient Ethernet to control energy efficiency in lower layers. In one example, an energy-efficiency control policy in a first Ethernet device can be configured to determine a need for transitioning of at least a part of the first Ethernet device into an energy saving sate. Based on such a determination, an energy-efficiency control signal can be transmitted from the first Ethernet device to a first non-Ethernet device. The receipt of the energy-efficiency control signal by the first non-Ethernet device is used to initiate a transition by the first non-Ethernet device into an energy saving state, which in turn may initiate a transition by downstream non-Ethernet devices into an energy saving state. This process creates a single unified energy-efficiency policy domain.

    Abstract: 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.

    Abstract: In automotive networking applications, data about vehicle's environment can be used in conjunction with a control policy to manage the performance and power usage of a networked device. The control policy can dynamically adjust the balance between link power and performance of the device's communications interface by taking into account the vehicles current situation and user preferences, e.g. location, destination, speed, sensor status, or the like. Controlling the balance between link power and performance of networked devices can be important in maximizing power savings without unacceptably decreasing network performance.

    Abstract: 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 802.3AN 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.

    Abstract: Training, refreshing and/or updating Ethernet link partners for silent channels and/or silent directions of channels may be determined based on control parameters. This may be used to improve energy efficiency in Ethernet communication. Control parameters may comprise a default value and/or may be determined based on prior training, refreshing and/or updating. New values for the control parameters may be generated based on a magnitude of change between current and prior control parameter values or based on performance such as bit error rate. User input may be utilized to determine when to execute the training, refreshing and/or updating. The training, refreshing and/or updating may be done for one or more of a near-end crosstalk canceller, alien near-end crosstalk canceller, far-end crosstalk canceller, alien far-end crosstalk canceller and echo canceller. After the training, refreshing and/or updating, the silent channels may transition to active and/or may remain silent.
