Abstract: A load balancing method, device and system, where the method includes: determining, based on load statuses of respective probe channels on n paths between a source end and a destination end, a target path with a lightest load in the n paths, where a probe channel is used to transmit a probe packet that includes a bandwidth probe packet; sending a bandwidth probe packet to the destination end through a probe channel on the target path; receiving the bandwidth probe packet returned by the destination end; and sending, based on the bandwidth probe packet returned by the destination end, a to-be-transmitted data packet to the destination end through a data channel on the target path. Therefore, load balancing among a plurality of paths is implemented.

Abstract: In an embodiment, a source node assigns a first number to a probe data packet in a probe data flow in a sending sequence, where the first number is used to select a transmission path for the probe data packet. The source node sends the probe data packet in the probe data flow to a destination node at a first sending rate. Each time the source node receives a probe data packet backhauled by the destination node, the source node sends a service data packet in a service data flow, where the service data packet is assigned a second number corresponding to the probe data packet, and the second number is used to select a transmission path for the service data packet.

Abstract: The present discloser relates to a method for active noise cancellation. An example method includes: capturing an ambient sound to determine an ambient audio signal; and determining a working status, determining at least one corresponding wanted signal based on the working status, and then removing the at least one wanted signal from the ambient audio signal, to obtain a reference signal, where the wanted signal includes content of interest. The example method further includes determining a to-be-played signal based on the reference signal.

Abstract: This application discloses a method for controlling traffic in a packet-based network. In the method, after receiving a control packet from a transmit end, an intermediate node between the transmit end and the receive end sends a control packet at the head of a first control queue based on a first duration, wherein the first duration is obtained based on a committed burst size (CBS) and a first committed information rate (CIR), and the intermediate node is configured to send a packet of a first transmit end to a first receive end in the packet-based network.

Abstract: In a data reading operation, a first terminal in a distributed storage system obtains a first data identifier, which is a unique identifier of first data in the distributed storage system. The first terminal determines, based on the first data identifier, whether first data is local data. When the first data is not local data, the first terminal obtains a first identifier that uniquely identifies the first data in the distributed storage system. The first terminal obtains, based on the first identifier, a second identifier corresponding to the first data and associated with content of the first data. The first terminal obtains, based on the second identifier, a read address that indicates that the first data is stored at a second terminal in the distributed storage system. The first terminal then retrieves the first data from the second terminal.

Abstract: A signal processing apparatus is configured to preprocess a sound wave signal and output a processed audio signal through an electromagnetic wave. The signal processing apparatus includes: a receiving unit, configured to receive at least one sound wave signal; a conversion unit, configured to convert the at least one sound wave signal to at least one audio signal; a positioning unit, configured to determine position information related to the at least one sound wave signal; a processing unit, configured to determine a sending time point of at least one audio signal based on the position information and a first time point, where the first time point is a time point at which the receiving unit receives the at least one sound wave signal; and a sending unit, configured to send the at least one audio signal through the electromagnetic wave.

Abstract: Example data generation methods and apparatuses are provided. One example method includes obtaining, by a data generation apparatus, spatial object information. The data generation apparatus can then generate content information for describing the spatial object. The data generation apparatus can then generate azimuth information based on the spatial object information, where the azimuth information indicates an azimuth of a spatial object relative to the data generation apparatus. The data generation apparatus can then generate, based on the azimuth information and the content information, spatial sound data for playing a spatial sound, where a position of a sound source of the spatial sound corresponds to the azimuth information.
