Abstract: This application discloses a method of determining a network path and a network device. The method includes: determining a first reachable network path that uses a source node as a start point and a directly connected node of the source node as an end point; selecting a first node from a to-be-added node set to obtain a second reachable network path that uses the source node as the start point and the first node as a relay; and when there are m paths that use a same destination node as end points in the first and second reachable network paths, comparing the m paths based on n target factors to obtain a first dominant network path, and updating the first reachable network path based on the first dominant network path, where m≥2, and n≥2.

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: Embodiments of the present disclosure provide a network congestion control method, where the method includes: sending, by a transmit end device, forward probe packets to a destination device at a preset initialized rate, where some or all of the forward probe packets arrive at the destination device after being rate-limited forwarded by using a reserved bandwidth of an egress port of an intermediate device in a network; receiving return probe packets returned by the destination device, where the return probe packets correspond to the probe packets received by the destination device; and determining a data packet sending rate based on the received return probe packets, and sending a data packet at the data packet sending rate.

Abstract: The technology of this application relates to a communication method and apparatus. The communication method includes a data sending device obtaining to-be-sent data of a locally installed first application, where a destination address of the to-be-sent data is an address of a data receiving device. The data sending device determines an address or addresses of one or more network adapters of the data receiving device based on the address of the data receiving device, the data sending device encapsulates the to-be-sent data based on the network adapter address to obtain encapsulated data, and the data sending device sends the encapsulated data to the data receiving device through a plurality of links. A destination address of each link is one of network adapter addresses of the data receiving device, and a source address of each link is one of network adapter addresses of the data sending device.

Abstract: This application provides an image sensor (702) and image light sensing method. The image sensor (702) includes a red pixel (R), a green pixel (G), a blue pixel (B), and an invisible light pixel, where the red pixel (R), the green pixel (G), and the blue pixel (B) are large pixels, the invisible light pixel is a small pixel, and a light sensing area of the large pixel is greater than that of the small pixel. The red pixel (R), the green pixel (G), and the blue pixel (B) are arranged in a Bayer format. In this application, when color information is sufficient, light crosstalk caused by the small pixel to the large pixel can be reduced, and therefore a signal-to-noise ratio of the large pixel can be improved.
