| Abstract(in English) | In this paper, we propose a method for identifying the traffic of content delivery services based on flow information (e.g., 5 tuples). In addition, we propose a method for observing ISP-scale traffic in a lightweight manner. Besides flow information, we use BGP routing information and OSINT (Open Source INTeligence) information. Also, we measure the normal behavior at each observation point and determine the statistical threshold of the flow information to identify individual services. In this paper, we identify the traffic caused by content delivery services using the actual traffic of WIDE Backbone (AS2500). As a result, it is found that it is possible to identify the service traffic using only routing information when the content provider uses its own CDN and does not provide other services, and to narrow down the potential services using OSINT information when the service provider provides. When the service provider uses third-party CDNs (Content Delivery Networks), it is difficult to identify the services reliably without OSINT information associated with the service name. |
