| Abstract(in English) | Overlay networks achieve new functionality and enhance network performance by allowing routing to be controlled at the application layer. However, these approaches result in degradations of underlying networks due to the selfish behavior of overlay networks. In this paper, we investigate the stability of virtual network topology (VNT) control under the overlay networks that perform dynamic routing updates. We reveal that the dynamics of routing on overlay networks cause a high fluctuation in the traffic demand, which leads to significant instability of VNT control. To overcome the instability induced by the overlay routing, we introduce three extensions, utilization hysteresis, two-state utilization hysteresis, and filtering, to VNT control. Through simulations, we show that our methods achieve the stability against overlay routing without the loss of the adaptability for changes in the traffic demand. |
