Abstract

The method involves managing the number of copies for each content stored on a set of storage units, according to a duplication/deletion policy of the copies. The managing of the number of copies includes modifying the number of copies by duplication and/or deletion, to maintain a difference between a simultaneous access number and a maximum simultaneous access number. Independent claims are also included for the following: (A) a computer program product comprising instructions for executing contents storage managing method (B) an information storage unit (C) a device for managing storage of contents (D) a node of a communication network with a contents storage managing device.
