PROBLEM TO BE SOLVED: To allow a cache server to store content to be reproduced, with a large load of a distribution server, even when a distribution band is different in each content to be reproduced. SOLUTION: A cache server control device 600 acquires a distribution band, for each of a plurality of items of content to be reproduced. The distribution band is used when concurrently distributing the same content to be reproduced to a plurality of client terminals 20, when receiving distribution requests for the same content to be reproduced, from the respective plurality of client terminals 20. Then, the cache server control device 600 determines the number of cache servers 300 necessary for storing the content to be reproduced, on the basis of the acquired distribution band. The cache server control device 600 selects the cache servers 300 necessary for storing the content to be reproduced, and allows the selected cache servers 300 to store the content to be reproduced.
