Abstract: A control method for performing a multi-table join operation and a corresponding apparatus are disclosed. Fields in a table whose fields participating in a theta join operation and used in the query statement meet a first preset condition are decomposed, to obtain a plurality of first field groups, so that the theta join operation can be implemented in steps in a form of the plurality of field groups. This can reduce a data amount of Cartesian product calculation during one join operation, greatly reduce network transmission overheads, computing overheads, and memory overheads, and improve execution efficiency.

Abstract: Embodiments of this application disclose path traffic allocation methods and network devices. One of the disclosed path traffic allocation methods includes sending, by an ingress node, a measurement packet to an egress node on each of at least two paths, where the at least two paths are paths between the ingress node and the egress node, and the measurement packet on each path indicates path information of each path. The disclosed method further includes receiving, by the ingress node, a response packet from the egress node, where the response packet indicates traffic adjustment information of each path, and determining, by the ingress node, to-be-sent traffic on each path based on the traffic adjustment information of each path.

Abstract: A network device control method and a control apparatus. The control apparatus may collect first working data, where the first working data includes a first measurement value, a first performance value, and a first device running parameter. The control apparatus determines whether the collected first working data meets a trend of a first set, where the trend of the first set is that an increasing/decreasing trend of measurement values in a plurality of groups of working data in the first set is consistent with or contrary to an increasing/decreasing trend of performance values in the plurality of groups of working data.
