摘要： In certain embodiments, a forwarding device receives at least one service flow. The forwarding device obtains service information of the at least one service flow, where the service information of the service flow includes identification information of a network object to which the service flow belongs and M key performance indicators KPIs of the service flow. M is an integer greater than o, and the network object includes one or more devices. The forwarding device sends detection information to a first device, where the detection information includes the service information of the at least one service flow or a feature set obtained based on the service information of the at least one service flow. The detection information is used to detect whether the network object is in a faulty state.

摘要： In a forwarding fault location determining method, a controller receives a plurality of table search statistical results of a plurality of forwarding tables for a first service from one or more forwarders. The plurality of forwarding tables include a first forwarding table and a second forwarding table, and the first forwarding table is prior to the second forwarding table in terms of a search sequence. Subsequently, the controller determines that table search behavior of the first forwarding table for the first service is normal and table search behavior of the second forwarding table for the first service is abnormal. The controller determines, based on the determining result, that the second forwarding table is a faulty forwarding table for the first service.

摘要： The present disclosure relates to polar decoding methods and apparatus. One example method includes obtaining a polar code sequence, determining at least one first information bit length corresponding to a code length of the polar code sequence, and decoding the polar code sequence based on blind detection by using the code length and the at least one first information bit length. The at least one first information bit length is a part of a preset information bit length set corresponding to the code length. A remaining part of the preset information bit length set is at least one second information bit length. The at least one second information bit length is excluded from being used for the blind detection. Each second information bit length is less than one or more information bit lengths in the at least one first information bit length.

摘要： A method and an apparatus for determining a status of a network device are provided. A warning analysis device obtains a plurality of pieces of target key performance indicator KPI data of the network device within preset duration, processes the plurality of pieces of target KPI data to generate an element, forms the feature vector by using generated elements corresponding to the plurality of pieces of feature information, and analyzes the feature vector based on a preset warning analysis model, to determine the status of the network device. In this way, the status of the network device is determined by analyzing a plurality of pieces of target KPI data within a period of time, instead of by using only data at a moment. This improves the accuracy of determining the network device, so as to reduce an omission of a warning.
