Search for: [Description = "Content delivery network \(CDN\) is an efficient and inexpensive method to improve Internet service quality. In this paper we formulate an optimisation problem of replica location in a CDN using MPLS techniques. A novelty, comparing to previous work on this subject, is modelling the network flow as connection\-oriented and introduction of capacity constraint on network links to the problem. Since the considered optimisation problem is NP\-complete, we propose and discuss exact algorithm based on the branch\-and\-cut and branch\-and\-bound methods. We present results of numerical experiments showing comparison of branch\-and\-cut and branch\-and\-bound methods."]
