Abstract(in English) In the network virtualization, multiple virtual networks can be constructed independently on a physical network, and it is necessary to maintain the quality of service in each virtual network. In this paper, we propose an optimal topology design method based on network robustness. In the proposed optimal topology design method, at first, a service provider who owns the physical network receives a request for constructing a virtual network from an user. Then, the service provider designs the optimal topology of the virtual network that can satisfy the request by solving an optimization problem with genetic algorithm. In the genetic algorithm, each gene shows which links are used in the virtual network. In addition, by utilizing the nature of the pseudo-inverse matrix, we propose a rapid virtual network construction method that can avoid the redundant use of resources on the physical network. As a result, by using the proposed methods, the service provider can construct rapidly the virtual networks whose topology is the optimal. We evaluate the performance of the proposed methods with simulation and show the effectiveness of the proposed methods.
