Virtual Network Topologies Adaptive to Large Environmental Changes by Reconfiguring a Small Number of Paths

Abstract (in Japanese) (See Japanese page) 
(in English) 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 metric based on the evolution model in the changing environments. We evaluate our metric through simulation, and clarify that our metric identifies the virtual network that can handle significant traffic changes by reconfiguring only a small number of paths.
