Replica placement problems (RPPs) as one of the key technologies in the Content Distribution Networks have been widely studied. In this paper, we propose an optimization model with server storage capacity constraints for the RPPs. Furthermore, part of the objective function is represented as a Multiple Minimum Cost Flow Model for the first time.
