Abstract (in Japanese) (See Japanese page) 
(in English) This paper reports results of feasibility study about dynamic traffic control methods to re-route traffic into DDoS-attack mitigation devices. In this method, anomaly traffic is re-routed from a point close to the victim user into a DDoS attack mitigation device. For rerouting anomaly traffic, we evaluated some conventional forwarding techniques, such as LSP and GRE tunnel. As a result, we deployed hop-by-hop policy-routing technique and implemented a traffic control server which can support operations of the network. In this case, the traffic control server should manage the whole network and control routers for setting hop-by-hop policy-routes. So there is some possibility that the traffic control server become bottleneck in large-scale networks. To confirm scalability of the proposed method, we evaluated control time of the proposed method by using prototype systems. Consequently, regardless of the number of routers on each hop-by-hop policy-route, control time on the traffic control server is small so that the traffic control server will not become bottleneck.
