Abstract(in English) | A typical approach for constructing/reconfiguring a virtual network (VN) is to design an optimal topology and the amount of resources with a knowledge of the end-to-end traffic demand matrix. However, it is difficult to configure the optimal VN using the traffic demand matrix in a changing environment. In this paper, we develop a VN reconfiguration framework without using the traffic demand matrix. Our basic idea is to memorize a set of ``good" VNs, each of which works well for a certain traffic situation, and then retrieve one of the VNs suitable for the current traffic situation. In order to identify the current traffic situation, we apply a concept of Bayesian inference. We use the amounts of outgoing/incoming traffic at edge routers as the traffic information, which are available more easily than the traffic demand matrix. Furthermore, for a case where the performance of the VN is not adequate even though the identification succeeds, we incorporate a noise-induced VN reconfiguration method with our framework. Evaluation results show that our method can identify the traffic situation using the amounts of outgoing/incoming traffic at edge routers, which are available more easily than the traffic demand matrix, and successfully decreases the number of VN reconfiguration to reach a VN suitable for the traffic situation. |
