Abstract: A wireless local area network roaming method and a communications apparatus are provided, to improve a roaming effect of a terminal device in a wireless local area network. In the method, a control device selects, in place of a terminal device, an optimal roaming access point of the terminal device, to reduce a time consumed for determining the optimal roaming AP. After the optimal roaming access point of the terminal device is determined, an associated access point instructs the terminal device to attempt to roam to the optimal roaming access point. Because duration required for searching for the optimal roaming AP is reduced, a probability of data loss of the terminal device in a roaming process can be reduced, and a roaming effect of the terminal device in the wireless local area network is improved.

Abstract: A mapper node and a reducer node respectively run on different central processing units (CPUs) in a CPU pool, and a remote shared partition shared by the mapper node and the reducer node is delimited in the storage pool. The mapper node executes a map task to obtain a data segment, and stores the data segment into a remote shared partition. The reducer node directly obtains a to-be-processed data segment from the remote shared partition, and executes a reduce task on the to-be-processed data segment.

Abstract: A primary node-standby node data transmission method includes an indication that a control node obtains an operation log generated by a primary node, where the operation log includes at least one operation record, and each operation record indicates a record of performing, by the primary node, a write operation on a local cache or a storage unit in a storage device. The method further includes the control node determining a first storage unit set that corresponds to a first standby node, the control node determining a second storage unit set that corresponds to the at least one operation record, the control node obtaining an operation record from the operation log, and the control node sending the corresponding operation record to the first standby node, where the storage unit intersection set is an intersection set of storage units in the first storage unit set and the second storage unit set.
