Abstract: 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.

Abstract: Aspects of a method and system for reducing transceiver power via a variable number of channels are provided. In this regard, utilization and/or availability of network and/or device resources may be determined and a configuration of channels utilized for transmitting data may be determined based on the determined utilization and/or availability of resources. Accordingly, the number of channels over which data is communicated may be altered based on determined thresholds for the utilization and/or availability of resources. Moreover, the configuration of channels utilized for communicating data may be dynamically altered by monitoring changes to the utilization and/or availability of resources. For example, the number of channels may be altered based on available bandwidth on one or more channels, based on capacity and/or available space of one or more buffers, and/or based on available power or desired power consumption of a transmitter.

Abstract: A physical layer (PHY) in a network device may provide self-adapting power reduction based on monitoring of activity associated with an interface between the PHY and remaining components of the network device. The power management operations of the PHY may then be configured and/or adjusted based on that monitoring. The PHY may comprise an Ethernet PHY, which may support energy efficient Ethernet (EEE) features. The monitored interface may comprise a Media Independent Interface (MII) based interface. In instances where the monitored activity comprises outbound traffic, outbound data received via the interface may be buffered when at least one subcomponent of the PHY that is operable to support transmission of the outbound traffic is unavailable due to the power management operations. The buffering may be configured to last to allow sufficient time to reactivate the at least one subcomponent.

Abstract: Aspects of a method and system for reducing transceiver power via a variable signal constellation are provided. In this regard, an Ethernet PHY device may receive one or more signals indicative of a current state of an Ethernet link to which the PHY device is coupled and/or indicative of resources, such as power, available to the PHY device. Accordingly, a number of points comprising a signal constellation utilized to communicate data via the Ethernet link may vary based on the one or more signals. A current state of the link may comprise a bit error rate, a packet error rate, and/or utilization, in terms of bandwidth for example, of the link. Aspects of the invention may enable controlling, at least in part, power consumption of the PHY device may altering the number of points comprising the signal constellation.
