Abstract
Disclosed are a method and an apparatus for controlling data storage. The method includes: obtaining the number of copies of to-be-placed media content; inputting user set information, server set information, media traffic demand information, and network topology information that are collected into a joint optimization model that is based on server selection and traffic engineering to perform joint optimization, and obtaining output information; performing statistics collection on the output information to obtain user access statistics of the to-be-placed media content on each cache device; and placing, according to the user access statistics of the media content and the number of copies, the copies of the to-be-placed media content so that the copies of the to-be-placed media content are preferentially placed on a cache device having large user access statistics. Embodiments of the present invention also provide an apparatus for controlling data storage.
