Abstract: The present disclosure relates to data transmission methods, systems, and apparatuses. In one example method, a first device sends first information of a first data block to a second device. The second device searches, based on the first information, a first index for a second data block similar to the first data block, and sends second information of the second data block to the first device. The first device locally obtains, based on the second information, a reference block that is the same as the second data block, compresses a difference part of the first data block relative to the reference block to obtain first compressed information, and sends the first compressed information to the second device. The second device obtains the first data block based on the first compressed information and the second data block.

Abstract: An access point (AP) energy saving method and an AP relate to the field of communications technologies, and effectively implement energy saving for the AP. The method includes determining that an AP is not associated with any terminal and there is not any to-be-associated terminal within a preset time segment, and turning off, by the AP, an extended radio frequency circuit, where an operating frequency band of the extended radio frequency circuit is a wireless local area network (WLAN) frequency band other than a 2.4 gigahertz (GHz) frequency band.

Abstract: The present invention provides a monitoring record management technology, which is used to manage a monitoring record stored in a memory, where the monitoring record is used to monitor a chunk in a storage, and by reading at least one monitoring parameter from each monitoring record in the memory, monitoring records between which a monitoring parameter meets a threshold are combined or split. After the monitoring record management technology provided in the present invention is applied, the occupancy of the memory can be reduced or the accuracy of the monitoring record can be improved.

Abstract: In a method for storing index metadata associated with stored data, a storage device provides a first metadata storage unit and a second metadata storage unit, wherein a size of the first metadata storage unit is greater than a size of the second metadata storage unit. When a size of target data reaches a specified threshold, the storage device stores index metadata of the target data based on the first metadata storage unit. When the size of the target data is less than the specified threshold, the storage device stores the index metadata of the target data based on the second metadata storage unit.

Abstract: A data processing method in a storage system is provided. The method includes: when the storage system is under a first load, performing an inline deduplication operation; and when the storage system is under a second load, directly storing a received second data block without performing the inline deduplication operation, where the first load is less than the second load.
