Abstract: Embodiments of the present invention provide a method for processing a Layer 2 network loop, where the method includes: receiving a packet, and obtaining a source MAC address of the packet; when a latest port among ports that are associated with the source MAC address is inconsistent with a receiving port of the packet, determining that transition of the source MAC address occurs once; when the number of times of transition of the source MAC address reaches a preset transition threshold, sending a detection packet respectively through the ports that participate in the transition of the source MAC address; and when the detection packet is received, determining a port that receives the detection packet as a port at which a loop is generated. The present invention further provides an apparatus and a network device. By using the method, a port at which a loop occurs can be precisely determined.

Abstract: A plurality of thin film transistors (TFTs) and a plurality of photo detectors (PDs) are disposed inside a display component. The plurality of PDs convert detected light into electrical signals. The plurality of PDs and the plurality of TFTs are disposed on two opposite inner side surfaces of a same layer of the display component. Projections of the plurality of PDs and the plurality of TFTs on a first plane are alternately distributed, and the first plane is a plane on which the layer at which the plurality of PDs and the plurality of TFT layers are disposed is located. Fingerprint recognition accuracy can be improved by configuring a display screen including the display component provided in the embodiments of this application. In addition, PDs of different quantities are flexibly arranged, to ensure that a large region of the display screen can be used for fingerprint recognition.

Abstract: The present invention is applicable to and relates to the field of communications technologies, and provides a method for delivering a static route and an ultimate provider edge (UPE). The method includes: reading, by a UPE, a packet; and delivering a corresponding static route according to related information carried in the packet. The present invention avoids problems that when a site is deployed on a large-scale radio access network, a base station cannot operate normally and a data communications device repeatedly performs troubleshooting and debugging on site caused by differences between preliminary data planning and actual site deployment data. A static route is automatically delivered by processing a packet, thereby reducing manpower costs and avoiding occurrence of human errors.

Abstract: Embodiments of this application provide an organic light-emitting display panel and a display apparatus. A functional layer disposed on a first substrate in the organic light-emitting display panel includes an emissive layer and an optical filter layer. A pixel define layer is disposed between adjacent organic light-emitting units in the emissive layer. Black light-shielding blocks and color-blocking blocks in the optical filter layer are alternately arranged. The color-blocking blocks and the organic light-emitting units are disposed in a one-to-one correspondence manner. A region between adjacent black light-shielding blocks covers the organic light-emitting unit in a thickness direction of the organic light-emitting display panel. The pixel define layer is a black light-absorbing layer. The black light-shielding blocks and the color-blocking blocks in the organic light-emitting display panel and the display apparatus provided in embodiments of this application, may cooperate to reduce transmission of visible light from an external environment to an internal film layer of the organic light-emitting display panel, and allow light emitted by the organic light-emitting unit to pass through. Therefore, a reflectivity of the organic light-emitting display panel to external ambient light is reduced, and luminance of the organic light-emitting display panel is not reduced.
