    摘要: Aspects of a method and system for utilization of an reserved and/or out of band channel for maintaining a network connection are provided. In this regard, information relating to training of one or more link partners communicatively coupled to an Ethernet link may be exchanged via a reserved and/or out of band channel on the Ethernet link. The reserved and/or out of band channel may be an auxiliary channel as specified by the IEEE802.1AN standard. The reserved and/or out of band channel may be utilized for scheduling training of one or more of the link partners, determining which of the link partners require training, synchronizing training of the link partners, training the link partners based on changes in environmental conditions. The training may comprise configuring an echo canceller a far-end crosstalk canceller, and/or a near-end crosstalk canceller.

    摘要: A system and method for enhanced physical layer device autonegotiation. The autonegotiation process typically identifies the highest common denominator amongst various standardized modes of operation. Enhanced autonegotiation can be used to select a mode of operation that is not the highest common denominator. Enhanced autonegotiation can also identify a non-standardized mode of operation using next page messaging, additional physical signaling, or Layer 2 messaging.

    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.

    摘要: 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.

    摘要: A system and method for continual cable thermal monitoring using cable characteristic considerations in Power over Ethernet (PoE) applications. Cable heating in PoE applications is detected through changes in electrical characteristics of the cable itself. By periodically monitoring the electrical characteristics such as insertion loss or cross talk of the cable, it can be determined whether the cable has exceeded certain thermal operating thresholds.

    摘要: A system and method for using a physical layer device's discovery of cable shielding for PoE current capacity setting and temperature de-rating. Headroom in a particular cable installation is increased when it is determined that the physical layer device is coupled to a shielded cable, which more effectively removes heat from a bundled cable. By the determination of the type of cabling, the current capable of being carried over the cable can be increased and/or the temperature de-rating decreased due to the removal of limitations of worst-case cable assumptions.

    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 AN 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.
