“…Over the years the attention of many researchers has been devoted to Content Delivery Networks (CDNs) as these systems gained popularity in the field of content distribution. The main research trends about content delivery networks (CDNs) and user access paradigms are analyzed and presented in [3]; on the other hand, the study in [4] focuses specifically on the delivery of multimedia content through CDNs.…”

The delivery of multimedia contents through a Content Delivery Network (CDN) is typically handled by a specific third party, separated from the content provider. However, in some specific cases, the content provider may be interested in carrying out this function using a Private CDN, possibly using an off-sourced network infrastructure. This scenario poses new challenges and limitations with respect to the typical case of content delivery. First, the systems has to face a different workload as the content consumer are typically part of the same organization that is the content provider. Second, the offsourced nature of the network infrastructure has a major impact on the available choices for CDN design. In this paper we develop an exact mathematical model for the design of a Private CDN addressing the issues and the constraints typical of such scenario. Furthermore, we analyze different heuristics to solve the optimization problem. We apply the proposed model to a real case study and validate the results by means of simulation.
