A fault detection method, a network device, and a system are provided. The method includes: After a first network device receives, through a first forwarding path in an SR policy, a BFD packet that is sent by a second network device and that includes indication information of a SID list, the first network device determines, based on the indication information of the SID list, a second forwarding path that is reversely co-routed with the first forwarding path, and sends a response packet of the BFD packet to the second network device through the second forwarding path, so that the second network device can perform fault detection on the first forwarding path based on the response packet.

Fault detection method, network device, and system

A shift register, a drive method, a drive circuit, a display substrate, and a display device are provided. The shift register includes an input unit, a first control unit, a second control unit, an output unit, and a voltage stabilizing unit. The input unit is configured to provide a signal of a signal input end to a first node and a signal of a first power supply end to a second node. The first control unit is configured to control a signal of a fourth node. The second control unit is configured to provide a signal of a second power supply end to the first node. The output unit is configured to provide the signal of the first or the second power supply end to the output end. The voltage stabilizing unit is connected to the first node, fifth node, the output end, and the first power supply end.

A method includes a second system that determines a type of a first management Internet Protocol (IP) address, and sends, to a first system, first information used to indicate the type of the first management IP address; the first system determines the first management IP address based on the type of the first management IP address indicated by the first information, and releases a first correspondence between system identification information and the first management IP address to an advertisement system; the advertisement system sends the first correspondence to a network management system; and the network management system manages the first system based on the first correspondence.

Method related to sending management IP address and system

A communication method and an optical module are disclosed. In various embodiments the method includes generating, by an optical module, a first packet according to a service packet that passes through the optical module, wherein a source address of the first packet is the same as a source address of the service packet, and wherein a destination address of the first packet is the same as a destination address of the service packet; sending, the first packet in a transmission direction of the service packet; and receiving, a second packet sent by the network device, wherein the second packet indicates that the first transmission path from the optical module to the network device exists, and wherein the second packet instructs the optical module to communicate with a network management system by using the network device and the first transmission path.
