摘要： A method, a system, and a device for establishing a pseudo wire are disclosed in embodiments of the present invention and are applicable to the field of communications technologies. The method for establishing a pseudo wire in the embodiments of the present invention includes: receiving, by a switching provider edge at a bifurcation position, a label mapping message, obtaining information of the switching provider edge at the bifurcation position and information of at least two next hops or outgoing interfaces of the switching provider edge through parsing, comparing the information of the switching provider edge at the bifurcation position with information of a local device, and if the information of the switching provider edge at the bifurcation position matches with the information of the local device, establishing at least two pseudo wires from the switching provider edge according to the information of at least two next hops or outgoing interfaces. In the method in the embodiments of the present invention, a TPE only needs to send one label mapping message to establish at least two pseudo wires, thereby reducing a resource consumed by pseudo wire establishment. In addition, when an active pseudo wire is faulty, the switching provider edge at the bifurcation position may directly perform an active/standby pseudo wire switchover, so that a fast recovery switchover process of an active/standby pseudo wire is simplified, and segment protection of an MS-PW can be provided from the switching provider edge at the bifurcation position, thereby making better use of a network resource.

摘要： A method, an apparatus, and a system for determining a collection period, a device, and a storage medium are disclosed, and pertain to the field of machine learning technologies. In this method, a machine learning model is obtained by using a training dataset collected based on candidate collection periods of X features, and a candidate collection period of each of the X features is determined as a target collection period of each feature based on the obtained machine learning model and a first condition. Because the target collection period of each feature is greater than a minimum collection period of each feature, subsequently, if data is collected based on the target collection period of each feature, an amount of the collected data is reduced, to reduce collection load of a device and memory occupied by sampled data, thereby reducing time redundancy.

摘要： A device identification method, apparatus, and system are provided. A management device or a collection device first determines a network traffic feature of a to-be-identified device based on a first dataset. The first dataset includes a plurality of pieces of first data, and each piece of first data includes a data amount of a data packet that is of the to-be-identified device and that is collected within one first periodicity. Then, the management device or the collection device determines a device type of the to-be-identified device based on a device identification model and the network traffic feature of the to-be-identified device. In a device identification process, the to-be-identified device does not need to report information used to identify the to-be-identified device. Therefore, a service run on the to-be-identified device is not interrupted, and reliability of running the service by the to-be-identified device is high.

摘要： A method, an apparatus, a system, a device, and a storage medium for implementing terminal verification are provided, and belong to the field of communications technologies. In this method, a transmission feature of a terminal is reconstructed to verify the terminal. For example, if a difference between the transmission feature obtained through reconstruction and the transmission feature of the terminal is relatively large, it indicates that the transmission feature of the terminal is abnormal, and the terminal is an abnormal terminal. In this case, it is determined that the verification of the terminal fails. Because the terminal has a specific normal transmission feature, and the normal transmission feature is not easily spoofed, in this method, various of abnormal terminals can be accurately found through verification, thereby improving accuracy of terminal verification. In addition, because a spoofing terminal is one type of abnormal terminal, in this method, the spoofing terminal can also be accurately found through verification without using a manner in which an IP address of the terminal is simply verified, to prevent the verification of the spoofing terminal from succeeding.

摘要： This application discloses a network device, a data processing method, apparatus, and system, and a readable storage medium, and belongs to the field of computer technologies. The network device includes: a network interface configured to receive target data, a first processor configured to determine feature information of the target data, a second processor configured to perform preprocessing on the feature information, and a third processor configured to perform inference on a preprocessing result. In addition, the second processor is further configured to perform policy analysis based on an inference result. Therefore, in this application, processing such as data collection, feature extraction, preprocessing, inference, and policy analysis may be performed by using an independent network device, so that a large delay caused by data reporting is avoided, and data processing efficiency is improved. In addition, a small quantity of network transmission resources are occupied, so that costs of data processing are low, and data leakage is avoided in a transmission process. Therefore, security and reliability of the data processing are ensured.

摘要： Embodiments of the present invention relate to a network element health status detection method and device, and relate to the field of communications technologies. The method specifically includes: determining, by a detection device, sampled data of at least one key performance indicator KPI of a target network element in a first time window; obtaining, by the detection device, a fluctuation score of any KPI in the at least one KPI according to sampled data of the any KPI in the first time window and a steady state value of the any KPI; and determining, by the detection device, a health status of the target network element based on a fluctuation score of each of the at least one KPI. Therefore, a network element health status is determined by using single-point performance data of a network element and performance data in a network element time window. A problem of inaccurate judgment by considering only single-point moment performance data of the network element is resolved. Therefore, this solution can be used to identify the network element health status more accurately.
