Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we consider the resource optimization of virtual networks which have the subset of the resources of the physical network.
The physical network manager should provide his/her resources to virtual networks so that all virtual networks satisfies their requirements.
However, the demands in virtual networks may change in time, and the virtual network whose demands increase requires more resources.
Thus, re-optimization of resources is required. Though frequent resource re-optimization makes the network unstable, resource re-optimization should be completed immediately after the lack of resources occurs.

To solve this problem, we consider the resource optimization method based on the predicted demands.
Our method uses the idea of the Model Predictive Control(MPC), which is a method of process control with predicting the system dynamics.
Through numerical evaluation, we demonstrate that our method avoids lack of resources.
