Abstract (in Japanese) (See Japanese page) 
(in English) Our research group has proposed a VNT control method that is adaptive to traffic changes. The method is based on a dynamical system, called attractor selection, that models behavior where living organisms adapt to unknown changes in their surrounding environments and recover their conditions. However, since our previously proposed VNT control method
relies on the centralized calculation of system variables, the computational overhead drastically increases as the size of network increases. In this paper, we propose a distributed calculation method to construct a virtual network topology in IP-over-WDM networks. Our method is again based on the attractor selection model to achieve the adaptability, but the VNT calculation is performed in a distributed manner. Evaluation results show that our proposed method requires only 0.032 sec for each node calculation at 1000-node network, while it requires more than 1000 sec by our previously proposed VNT control method.
