摘要： A time limit may be determined for energy efficient networking (EEN) sleep intervals based on end-to-end sleep interval limitations. The time limit may be communicated to other network devices which may limit their sleep time. End-to-end sleep interval limitation information may be received via a user input, packet header information, a standardized and/or non-standardized network management protocol, AVB, SRP, RSVP and SNMP. The EEN sleep interval time limit may be determined based on a number of hops between endpoint devices. Packets may be inspected to determine a packet data type and/or end-to-end sleep interval limitation information. The time limit may be determined based on latency requirements of data streams. A time limit for a port may be determined based on sleep time limits for data streams communicated via the port. The time limits may be statically and/or dynamically configured. The network device may be configured via a network management interface.

摘要： A method and system to dynamically manager power in a communication system are provided herein. The method comprises the steps of monitoring a transmit data queue once every first pre-determined period of time and determining whether the transmit data queue is empty for a pre-determined number of times. The method further includes the step of generating a transition state signal to stop de-queing of data from the transmit queue if the transmit data queue is empty for the pre-determined number of times and selectively operating portions of a Physical Layer (PHY) that are used for functions other than transmitting and receiving an idle signal in a low power mode.

摘要： End-to-end communication in a communications network is controlled by determining, based on monitoring of traffic in the communications network, the number of paths, or links, needed between the first and the at least second network element. If it is determined, based on the traffic load, that not all available paths are needed:—Selecting at least one path that should not be used to carry traffic,—Rerouting any traffic using the selected at least one path to at least one alternative path, and—Placing any network elements or links not carrying traffic after the rerouting in standby mode in which the power consumption of the elements is reduced, to reduce the power consumption in the network.

摘要： A system and method for energy efficient Ethernet (EEE) enhanced information technology power management tools. EEE-based computing center resources are designed to monitor energy savings events hardware components (e.g., physical layer device) included within the computing center resource. Energy saving statistics based on such monitoring can be provided to a power management tool. This monitoring information enables the power management tool to make broad service-level energy savings decisions on actual network activity. In addition, feedback based on the broad service-level energy savings decisions can be provided to the EEE-based computing center resources for consideration by their individual EEE control policies.

摘要： In one embodiment, a modified local PHY is adapted to couple a legacy host device to link partner implementing Energy Efficient Ethernet. The modified local PHY includes a buffer and if the legacy host transmits data when the modified local PHY is in a Low Power Idle (LPI) state then the data is stored in the buffer and transmission is paused until the modified local PHY transitions from the LPI state to an active state.

摘要： A power line adapter and its controlling method to be operated in a power-saving mode are disclosed. The power line adapter includes a power-transmitting module for generating a DC supply voltage and a data-transmitting module for transmitting data. Furthermore, the data-transmitting module at least includes a power line communication circuit and an Ethernet physical layer transceiver. The controlling method comprises steps of: monitoring a link signal generated by the Ethernet physical layer transceiver when the power line adapter is operated in an active mode; and, disconnecting the DC supply voltage to the power line communication circuit and entering the power-saving mode if the link signal indicates a disconnection over a first time period.

摘要： One embodiment of the present invention provides a system that wakes up a sleeping target system located on a target LAN (Local Area Network) from a remote system located on a remote LAN. Note that, since the sleeping target system is in a sleep state, it receives packets of a lower-layer protocol which cannot be used by the remote system to directly send packets to the sleeping target system. During operation, the remote system creates a wake-up packet. The remote system then uses a second protocol to send the wake-up packet to a relay agent located on the target LAN. Note that using the upper-layer protocol enables the remote system to communicate with the relay agent even though they are on different LANs. Upon receiving the first wake-up packet, the relay agent uses the lower-layer protocol to send a second wake-up packet to the sleeping target system, which causes the sleeping target system to wake up. Recall that the remote system cannot use the lower-layer protocol to send a wake-up packet directly to the sleeping target system because the remote system and the sleeping target system are on different LANs. The remote system overcomes this limitation by first sending a wake-up packet to the relay agent using the upper-layer protocol, which causes the relay agent to send another wake-up packet to the sleeping target system using the lower-layer protocol. The lower-layer protocol is preferably Ethernet, the upper-layer protocol is preferably IP. The relay agent is preferably a DHCP relay agent, such as an IP router.
摘要翻译：本发明的一个实施例提供一种从位于远程LAN上的远程系统唤醒位于目标LAN（局域网）上的睡眠目标系统的系统。注意，由于睡眠目标系统处于睡眠状态，所以接收到远程系统不能使用的低层协议的分组直接向睡眠目标系统发送分组。在操作期间，远程系统创建一个唤醒数据包。然后，远程系统使用第二协议将唤醒分组发送到位于目标LAN上的中继代理。请注意，使用上层协议使远程系统能够与中继代理通信，即使它们位于不同的LAN上。在接收到第一个唤醒分组时，中继代理使用下层协议向睡眠目标系统发送第二个唤醒分组，这导致睡眠目标系统唤醒。回想一下，由于远程系统和睡眠目标系统在不同的LAN上，远程系统不能使用低层协议将唤醒数据包直接发送到睡眠目标系统。远程系统通过首先使用上层协议向中继代理发送唤醒分组来克服这个限制，这使得中继代理使用较低层协议向休眠目标系统发送另一个唤醒分组。较低层协议优选为以太网，上层协议优选为IP。中继代理优选地是DHCP中继，例如IP路由器。
