Abstract: An information sharing method and related terminal device are provided. In the method, a first terminal device first establishes a communication connection to a second terminal device. When the first terminal device approaches a third terminal device, the first terminal device performs identity authentication on the third terminal device through near field communication (NFC). After determining that the identity of the third terminal device is valid, the first terminal device sends communication link information to the third terminal device by using a short-range wireless communication technology. After receiving the communication link information, the third terminal device establishes a communication connection to the second terminal device by using the communication link information when detecting the second terminal device. In the foregoing solution, communication connections can be quickly and conveniently established, and information sharing can be implemented among a group of terminal devices.

Abstract: A link fault detection method includes sending, by a first network device, data traffic to a second network device by using a plurality of first label switched paths (LSPs). The method also includes determining, by using each of the plurality of first LSPs within a preset period, whether a first link detection packet from the second network device is received. The method further includes determining an LSP of the plurality of first LSPs for which the first link detection packet is not received as a first faulty LSP. The method additionally includes calculating a first unavailability of the plurality of first LSPs based on the first faulty LSP. The method also includes triggering the plurality of first LSPs to stop transmitting the data traffic according to the first unavailability of the plurality of first LSPs.

Abstract: This application relates to the field of communication technologies, and provides a packet processing method, apparatus, and system, and a computer-readable storage medium. The method is applied to a user plane (UP) device of a virtual broadband network gateway. The UP device receives a first packet sent by a control plane (CP) device, where the first packet carries first indication information, and the first indication information indicates the UP device to perform online management on a terminal device that accesses a network through a virtual broadband network gateway; determines a proxy lease of a first terminal device based on the first packet, where the first terminal device is the terminal device that accesses the network through the virtual broadband network gateway; and performs online management on the first terminal device based on the first indication information and the proxy lease of the first terminal device.
