Abstract: One example packet processing device includes a buffer, and the packet processing device obtains a to-be-measured packet. In response to determining that occupied storage space in the buffer is less than a preset threshold, the packet processing device reads the to-be-measured information from the buffer, and modifies, based on the to-be-measured information and a first algorithm, a pieces of data in first measurement data corresponding to the to-be-measured packet, where a is a positive integer. In response to determining that occupied storage space in the buffer is greater than or equal to a preset threshold, the packet processing device modifies, based on to-be-measured information and a second algorithm, w pieces of data in second measurement data corresponding to the to-be-measured packet, where w is a positive integer, and w is less than a.

Abstract: A data processing method is disclosed, and the method includes: encoding a data chunk of a predetermined size, to generate an error-correcting data chunk corresponding to the data chunk, where the data chunk includes a data object, and the data object includes a key, a value, and metadata; and generating a data chunk index and a data object index, where the data chunk index is used to retrieve the data chunk and the error-correcting data chunk corresponding to the data chunk, the data object index is used to retrieve the data object in the data chunk, and each data object index is used to retrieve a unique data object.
