“…Infrastructure nodes and links provide a given amount of computing, storage, and possibly wireless resources (a c , a m , a w ), expressed in number of CPUs, Gbytes, and Gbps, depending on the layer they are located. The per-unit resource cost (c n (i), ∀n ∈ Υ and c b (ij)), the node disposal cost c f (i), and the fixed cost c d (i) are set respectively to 1, 50, and 20, In each time slot k, we assume that a random part of the infrastructure resources are partly consumed by besteffort background services, see [5]. The performance of the proposed provisioning variants are evaluated considering different network conditions in terms of resource consumption by background services.…”
