SUMMARY:Network Function Virtualization\; Techno-Economics
DESCRIPTION:Network Function Virtualization (NFV) is an emerging
 approach\nthat has received attention from both academia and industry as a
 way to\nimprove flexibility\, efficiency\, and manageability of networks.
 NFV\nenables new ways to operate networks and to provide composite
 network\nservices\, opening the path toward new business models. As in
 cloud\ncomputing with the Infrastructure as a Service model\, clients will
 be\noffered the capability to provision and instantiate Virtual
 Network\nFunctions (VNF) on the NFV infrastructure of the network
 operators. In\nthis paper\, we consider the case where leftover VNF
 capacities are\noffered for bid. This approach is particularly interesting
 for clients\nto punctually provision resources to absorb peak or
 unpredictable\ndemands and for operators to increase their revenues. We
 propose a game\ntheoretic approach and make use of Multi-Unit Combinatorial
 Auctions to\nselect the winning clients and the price they pay. Such a
 formulation\nallows clients to express their VNF requests according to
 their\nspecific objectives. We solve this problem with a greedy heuristic
 and\nprove that this approximation of economic efficiency is the
 closest\nattainable in polynomial time and provides a payment system
 that\nmotivates bidders to submit their true valuations. Simulation
 results\nshow that the proposed heuristic achieves a market valuation close
 to\nthe optimal (less than 10 % deviation) and guarantees that an
 important\npart of this valuation is paid as revenue to the operator. Joint
 work\nwith Jean-Louis Rougier\, Luigi Iannone\, Mathieu Bouet and Vania
