| Outline of Final Research Achievements |
In this research, we proposed a topology design of virtual networks and traffic engineering over virtual networks for fast failure recovery and low-energy consumption. In the proposed topology design, network topology whose number of used links is small is designed with the optimization problem by considering graph theory. In this design, the amount of traffic is also considered for the topology design. Moreover, in the traffic engineering, the route selection probability is derived with the optimization problem to transmit data based on the traffic load on each link.
