Media Edge Cloud Data Centers (MEC-DCs) that are interconnected by a Metro Network were selected as\ninfrastructure to enhance the Quality of Experience (QoE) for end users of multimedia applications. Unlike the\ntraditional Data Centers, MEC-DCs, which are kept closer to the user, have limited availability of resources at a given\nData Center. Therefore, it is of paramount importance for Infrastructure service providers to efficiently dimension and\nuse the media resources in an environment where the applications have high resource demand and the infrastructure\nhas limited availability. To perform this task dynamically, we first propose a resource allocation strategy that considers\nthe physical characteristics of the networking layer while minimizing the costs of deploying media applications.\nSecond, we analyze the different configurations of the networking layer in order to enhance the use of MEC-DCs\nresources and the QoE for the end-users. Simulation results show a clear advantage of this proposed\noptimization-based approach over the benchmarks in terms of provisioning costs, blocking ratio and resource use.
