Abstract:
A virtual network reconfiguration is one efficient approach to accommodate the traffic that changes significantly. By reconfiguring the virtual network, the network accommodates the traffic even when the traffic pattern changes significantly. The reconfigure has a large impact on the traffic passing the reconfigured paths. Thus, the number of reconfigured paths should be minimized. The number of reconfigured paths depends on the virtual network topology before the reconfiguration, and some topology requires a large number of reconfigured paths to handle the traffic changes. In this paper, we investigate the virtual network topology, which can handle significant traffic changes by reconfiguring only a small number of paths. To investigate the virtual network, we propose a index based on the evolution model in the changing environments. We evaluate our index through simulation, and clarify that our index indicates the adaptability of virtual networks. We also compare our index with betweenness centrality, and clarify that our index identifies the virtual network with high adaptability to traffic changes more accurately.
