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.

Traffic measurement method, device, and system

The present disclosure relates to data access methods and apparatus. One example method includes sending, by a first cache server, a first access request to a second cache server, where the first access request is used to request first data, and the first access request is from a first edge server, receiving, by the first cache server, a copy of the first data and a first access frequency that are returned by the second cache server, where the first access frequency is a frequency at which the first edge server accesses the first data and that is recorded by the second cache server, determining, by the first cache server, whether a second access frequency lower than the first access frequency exists, and in response to determining that the second access frequency exists, caching, by the first cache server, the copy of the first data.
