    Abstract: An electrical connection apparatus includes a cable connector, a PCB, and a fastened wall. The cable connector includes a connecting terminal and a plurality of first contacts. One part of each first contact is located in the connecting terminal, and the other part extends from the connecting terminal. The printed circuit board includes a substrate and a plurality of second contacts. The plurality of second contacts are located on a surface of the substrate. The fastened wall includes a plurality of sidewalls. The plurality of sidewalls are fastened to the substrate, and are located on at least two opposite sides of the plurality of second contacts. When the cable connector and the PCB are fitted, the cable connector and the fastened wall are detachably fastened, and the first contact and the second contact are in close contact.

    Abstract: 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.

    Abstract: An alarm log compression method, apparatus, system, and a storage medium are provided. The method includes: obtaining a historical alarm log set generated by a first network device; dividing the historical alarm log set into a plurality of historical alarm log subsets based on a generation time stamp of a historical alarm log in the historical alarm log set, where all historical alarm logs in each historical alarm log subset are consecutive in a time sequence; determining a correspondence between an alarm type in the historical alarm log set and the plurality of historical alarm log subsets; performing clustering processing on the alarm types in the historical alarm log set based on the correspondence, to generate at least one association rule; and compressing to-be-processed alarm logs based on the at least one association rule, to obtain an alarm log whose alarm type is a root cause alarm type.

    Abstract: 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.

    Abstract: 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.
