| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In the Society 5.0, it is important to accurately measure and analyze the communication traffic flow in wide-area IP networks, and to be able to promptly detect communication anomalies for achieving sustainable social infrastructure. However, in wide-area IP networks, communication traffic flow is encapsulated by headers assigned by communication carriers, and thus is observed as more macroscopic information. Therefore, it is difficult to accurately detect the occurrence of anomalies for an individual communication flow because the flow observation results obtained by flow measurement protocols such as IPFIX are the result of superimposing various communication flows with different characteristics. In this paper, we propose a method of anomaly analysis and detection method from time-series traffic flows. First, we decompose superimposing traffic flows into individual flows by using our implementation of the Fast xFlow Proxy, which can decompose communication traffic flows to a fine granularity. Then, our algorithm detects anomalies from decomposed flows based on correlation analysis. We report the results of a simulation evaluation of the proposed method, which shows that it can achieve anomaly detection quickly and accurately. | |
