Abstract: A data transmission method and apparatus, a device, and a storage medium are provided. The method includes: receiving a first packet sent by a second device, where the first packet includes a plurality of second packets, each second packet in the plurality of second packets carries service data, a time sequence attribute of the second packet, and a sequence number of the second packet, and the time sequence attribute indicates whether the service data needs to be added to a waiting queue; and when the time sequence attribute of the second packet is a blocking attribute, adding the service data carried in the second packet to the waiting queue; or when the time sequence attribute of the second packet is a non-blocking attribute, uploading the service data to an application layer of a first device.

Abstract: A network device and a vertical interface are disclosed. The network device includes a panel (31), a printed circuit board PCB (32), and N vertical interfaces (33). The vertical interface is an interface whose width is less than a height. The panel is connected to the PCB, and the panel includes N vertical openings, where N is greater than or equal to 2. Each of the N vertical interfaces includes a housing (331), a connection component (332), and a connector (333). The housing is configured to accommodate the vertical interface into the panel by using one of the N vertical openings on the panel. The connection component is configured to connect the vertical interface to the PCB. The connector is configured to transmit a signal to the PCB by using the connection component.

Abstract: Methods and devices are provided for identifying a terminal. In the method, the device receives a request for accessing a target webpage sent by the terminal. The device sends preset drawing information to the terminal, where the preset drawing information may instruct the terminal to draw a corresponding object according to the preset drawing information. The device acquires object information for characterizing the object drawn by the terminal and generates identification information for identifying the terminal according to the object information.

Abstract: The present invention relates to network management and discloses a system, method, and device for Automatic Protection Switching (APS). The system includes a sending device and a receiving device. The sending device includes a first sending line card and a second sending line card. The receiving device includes a first receiving line card and a second receiving line card. In the embodiments of the present invention, the first receiving line card and the second receiving line card check arrival of continuity check messages, and perform centralized switching control on the line cards automatically according to the check result, thus improving APS efficiency and reliability of a PS-based transport network.
