Cost Efficient VNF Placement with Optimization Problem for Security-Aware Virtual Networks

In this paper, we propose cost efficient VNF placement with optimization problem for embedding security-aware virtual networks. In this method, some VNFs are placed in order to increase the security level of virtual networks. Moreover, virtual networks are embedded and VNFs are placed with cost optimization. We evaluate the performance of the proposed method with simulation. In numerical examples, we show that virtual networks can be embedded based on security level with less resources by using the proposed method.
