Abstract (in Japanese) (See Japanese page) 
(in English) An anomalous traffic change in traffic distributions caused by external inter-domain routing change leads to congestion of some network links, which then affects the network quality or disrupts traffic. Thus, network operators need to promptly deal with problems by changing the routing policy or by soliciting help of an involved or neighboring network operator through operator channels. In addition, they need to diagnose situations in which customers are affected by the incident or in which destinations become unreachable. Although this task is indispensable, understanding the situation is difficult due to the cause being from outside the operators’ network domains. To alleviate the load on operators, we developed a monitoring system for traffic shift and disruption caused by BGP routing change. It is challenging to extract information that is more valid from a large amount of BGP update messages and traffic flow records. By correlating these data, the system provides meaningful reports and visualized traffic statistics, and it enables operators to easily detect traffic changes and to investigate the extent of damage. We demonstrate the effectiveness of the system and evaluate its feasibility by applying it to an ISP backbone network. In addition, we present a case study of traffic changes that the system detected. And we analyzed the network level behavior of spam mail and ham mail using the traffic shift monitoring system, and demonstrate the visible differences.
