Abstract: A data transmission method, apparatus, and system are applied to the field of communication technologies. The method includes: performing demultiplexing processing on obtained y first data streams to obtain x second data streams, where the y first data streams are obtained through bit multiplexing processing; mapping the x second data streams at a granularity of n bits to obtain z third data streams; and outputting the z third data streams over an output lane, where y, x, n, and z are all positive integers, and n≥2. The method may be applied to an Ethernet high-speed interface.

Abstract: A power over Ethernet (PoE) power supplying method where power sourcing equipment (PSE) and a powered device exchange link layer discovery protocol data units (LLDPDUs). Each of the LLDPDUs includes two power values. Each of the power values indicates requested or allocated power for one of two sets of cable pairs of the Ethernet twisted pair connecting the PSE and the powered device. Accordingly, the supplied powers to the powered device at sets of cable pairs are independent from each other.

Abstract: An energy conservation management method includes selecting, by a policy server, a target scenario model from a plurality of scenario models based on a plurality of scenario attribute values of a target network, and configuring, by the policy server, a network device in the target network based on an energy conservation policy of the target scenario model. At least one of the plurality of scenario attribute values is an attribute value of a scenario attribute related to a network power consumption of the target network. The at least one of the plurality of scenario attribute values includes a plurality of attribute values of a corresponding scenario attribute, wherein each of the plurality of attribute values is collected at a different time from other attribute values of the plurality of attribute values that are collected at different times.

Abstract: A sampling assembly and a sampling method are provided. A self-calibration unit controls a first switch to be turned on, to enable a first sampling signal to be input to a sampling unit. The sampling unit processes the first sampling signal to obtain a second sampling signal, and outputs the second sampling signal to the self-calibration unit. The self-calibration unit controls the first switch to be turned off, controls a second switch to be turned on, and outputs a first calibration signal to the sampling unit. The sampling unit processes the first calibration signal to obtain a second calibration signal, and outputs the second calibration signal to the self-calibration unit. The self-calibration unit determines an error signal based on the first calibration signal and the second calibration signal. The self-calibration unit obtains a calibrated third sampling signal based on the second sampling signal and the error signal.
