摘要： A system and method for energy savings through emulation of wake on LAN (WoL) in energy efficient Ethernet networks. An intermediary device between a computing device and a network can be alerted that the computing device has entered an energy saving state with wake on LAN (WoL) enabled. The intermediary device can transition the client interface that supports the computing device into an energy saving state and emulate the WoL function of the computing device by listening for a WoL message destined for the computing device. Upon receipt of a WoL message destined for the computing device, the intermediary device can transition the client interface back to an active state then transmit the received WoL message to the computing device.

摘要： A method is disclosed of centralized Power over Ethernet network shutdown, that comprises the steps of:
- sending (19) from a centralized management unit (1, 2) through said network a shutdown binary signal, a first value of which commands a shutdown, and the second value of which authorizes a restart;
- detecting (20) the value of said shutdown signal, in a network element;
- then shutting down (22, 24) at least some of the functions of said network element and propagating the shutdown signal, if the signal has its first value, or authorizing all the functions of said network element if the signal has its second value.
The shutdown signal can be constituted by a Power over Ethernet voltage usually used for remotely supplying power to network elements that can be remotely powered. The presence of a Power over Ethernet voltage commands a shutdown, and commands the propagation of a shutdown signal; whereas the absence of the Power over Ethernet voltage authorizes all the functions of said network element.

摘要： Aspects of a method and system for managing an energy efficient network utilizing Audio Video Bridging are provided. In this regard, an Audio Video Bridging timeslot may be designated for handling an energy efficient networking (EEN) transaction and the EEN transaction may be performed during the designated timeslot. Exemplary EEN transactions comprise scheduling a data rate transition, transitioning to a different data rate, training a link partner, and exchanging training related information. It may be determined whether the timeslot may be reserved for conveying an AVB stream prior to designating the time slot for an EEN transaction. In instances that the timeslot may be unreserved, the timeslot may be reserved for EEN transaction(s). Information exchanged during the designated timeslot may enable scheduling a data rate transition and/or training on a network link. In this regard, a subsequent timeslot may be designated for the data rate transition and/or the training.

摘要： A method and apparatus for reducing power consumption of an auto-negotiating ethernet transceiver by enabling a driver for the transceiver to alternate between a typical higher-power energy consumption mode to a lower-power energy consumption mode when a network link is no longer detected by the transceiver. A new algorithm is included within the driver which is activated by the driver detecting the absence of the network link. The driver causes the portable computer to send instructions to the ethernet transceiver so that the transceiver continues to check for the network link. If the network link is not detected, the driver causes the ethernet transceiver to power down into a lower power consumption mode for a specific period of time. After the period of time has elapsed, the driver causes the ethernet transceiver to enter a normal higher power consumption mode during which the ethernet transceiver again checks for the network link. This process repeats itself until the portable computer is shut down or the network link is reestablished.

摘要： A media access controller (100) having a power-saving feature. The controller (100) comprises a receive logic circuit for receiving incoming data from a physical interface device (104) and processing the incoming data for transmission to a frame processor (102), and a transmit logic circuit for receiving outgoing data of the frame processor (102) and processing the outgoing data for transmission to the physical interface device (104). A power management control logic (114) operatively connects to each of the receive logic circuit and the transmit logic circuit to control the receive logic circuit and the transmit logic circuit in a first mode or a second mode. The power management control logic (114) controls the media access controller (100) in the first mode to conserve power by stopping operation of substantial portions of both the receive and transmit logic circuits, and in the second mode, which is a full power mode, by running both the receive and transmit logic circuits.

摘要： One of the fundamental benefits of the 10BASE-T physical interface for 802-3/Ethernet is that the health of the communications link can be permanently monitored. When in the "link good" condition, the 10BASE-T transceiver is required to output a link status (LNKST) signal to this effect. Media Access Controller (MAC) 30, with an embedded 10BASE-T transceiver (37), uses the LNKST signal to provide power management to the MAC (30). By using the programmable AWAKE bit, the receive section of the 10BASE-T transceiver (37) can remain powered, even if the SLEEP input to the MAC (30) is activated. This allows the transceiver (37) to detect a link beat pulse (60) or receive packet activity. If either receive condition is encountered, the internal transceiver (37) will activate the LNKST output from the MAC (30). The system hardware and/or software can use the LNKST output to take appropriate action. For instance, if the LNKST output is active (low), then the computer is connected to an active network, and it is likely that the operating system will allow the MAC (30) to remain powered. However, if the LNKST becomes inactive (high) then the system can assume that the link is inactive, and the MAC can be powered down to save power. If at a later time the link is re-established, the MAC (30) can be powered back up to take advantage of the communications channel. In this way, the power consumption of the Ethernet connection can be managed by the operating software/hardware.
