Abstract:
Virtual Network Topology (VNT) is one efficient way to transfer IP packets over wavelength-routed optical networks. In recent years various new services have emerged, and IP traffic has been highly fluctuated. Therefore, adaptability against changes of traffic is one of the most important characteristics to accommodate the IP traffic efficiently. To achieve the adaptability, we have proposed a VNT control method using an attractor selection model. In this paper, we investigate the adaptability of our VNT control method via computer simulations. Simulation results on various physical topologies indicate that our VNT control method can successfully adapt to changes of traffic around twice higher variance comparing with conventional VNT control methods. We also demonstrate that our VNT control method achieves one-tenth of control duration.
