Abstract: This application provides an optical link fault identification method, and relate to the field of communications technologies. The method includes: obtaining performance data of a network device, extracting a feature parameter of the performance data, and identifying a fault mode on an optical link based on the feature parameter. The method resolves problems of a difficulty in fault identification and slow troubleshooting that are caused by a large quantity of devices, many line faults, and a difficulty in obtaining manual troubleshooting cases. In addition, a fault can be quickly identified when the fault occurs, improving troubleshooting efficiency. When an optical link risk does not cause a fault, deterioration of the performance data can be found in advance based on a feature, to perform identification and warning.

Abstract: An air deflection system includes a cabinet and an air deflection cabinet. The cabinet includes a cabinet first air vent on a lower part of a cabinet first side, a cabinet second air vent at a top of the cabinet, and a cabinet third air vent on a cabinet second side for cool air to enter. The air deflection cabinet includes an air deflection cabinet first air vent at a top of the air deflection cabinet and an air deflection cabinet second air vent on an air deflection cabinet first side that is proximate to the cabinet first side. The air deflection cabinet second air vent is in communication with the cabinet first air vent such that warm air exhausted through the cabinet first air vent enters the air deflection cabinet through the air deflection cabinet second air vent and is exhausted through the air deflection cabinet first air vent.

Abstract: A method determines, by using a multi-stream association mechanism, whether an attack succeeds. Attack data and an identifier of an attacked host are obtained from a data flow in which an attack event is detected. The attack data and the identifier of the attacked host are used to associate the data flow in which the attack event is detected with another data flow transmitted after the data flow. Whether the attack succeeds is determined based on whether the data flow is associated with the another data flow. According to the method, whether the attack succeeds can be determined in a scenario in which there is no echo on a server or response content does not include an execution result of the attack data.
