Abstract: In one embodiment, a retimer device includes a receiver to receive data from a first device via a data link, retimer circuitry to recover a clock phase from the received data, and prepare a new copy of the received data sampled by a clean clock based on the recovered clock phase, a transmitter to transmit the new copy to a second device via the data link, wherein the receiver is configured to receive an in-band standby signal from the first device having a given pattern in a physical layer of the signal, activate a power saving mode of the retimer device responsively to the standby signal having the given pattern in the physical layer of the standby signal, receive an in-band wakeup signal from the first device, and initiate an exit from the power saving mode to power up the retimer device responsively to the wakeup signal.

Abstract: In one embodiment, a network device includes frequency generation circuitry configured to generate a clock signal, a phase-locked loop (PLL) configured to generate a local clock based on the clock signal, a plurality of receivers configured to receive respective data streams from respective remote clock sources, each receiver of the plurality of receivers being configured to recover a remote clock from a respective data stream, and a controller configured to identify the remote clock recovered by one of the plurality of receivers as a master clock, find a clock differential between the identified remote clock and the local clock, and provide a control signal to the frequency generation circuitry responsively to the clock differential, which causes the frequency generation circuitry to adjust the clock signal so as to iteratively reduce an absolute value of the clock differential.

Abstract: A network device includes a plurality of ports, processing circuitry, and control circuitry. The ports are to receive communication traffic from a plurality of processing devices. The processing circuitry is to process the communication traffic received via the ports. The control circuitry is to assess one or more electrical-current consumption values associated with at least the network device, and, depending on the electrical-current consumption values, to control a traffic slew-rate of the communication traffic of at least a port among the ports to remain within a specified slew-rate range, the traffic slew-rate being defined as a rate at which a bandwidth of the communication traffic received via the port changes as a function of time.

Abstract: A network element includes at least one communication port and a processor. The communication port is configured to communicate with a peer communication port of a peer network element. The processor is configured to support a full-boot mode and a fast-boot mode, to establish, by negotiation with the peer network element, whether the fast-boot mode is supported both for the communication port and for the peer communication port, and, in response to finding that the fast-boot mode is supported both for the communication port and for the peer communication port, to coordinate with the peer network element a boot of the communication port and of the peer communication port, both using the fast-boot mode.

Abstract: A method for processing data includes receiving in a peripheral device, which is connected by a bus to a host processor having host resources, a notification of a sleep state of at least one of the host resources. While the at least one of the host resources is in the sleep state, when the peripheral device receives data from a data source for delivery to the host processor, the peripheral device sends a message to the data source, which causes the data source to defer conveying further data to the peripheral device until the at least one of the host resources has awakened from the sleep state.
Abstract translation: 一种用于处理数据的方法包括：在通过总线连接到具有主机资源的主处理器的外围设备中接收至少一个主机资源的睡眠状态的通知。 当主机资源中的至少一个处于睡眠状态时，当外围设备从数据源接收数据以传送到主处理器时，外围设备向数据源发送消息，这导致数据源延迟 将进一步的数据传送到外围设备，直到主机资源中的至少一个已经从睡眠状态唤醒。
