Abstract (in Japanese) (See Japanese page) 
(in English) uRPF is widely used technology to filter source IP spoofed packets, using route information. With uRPF filtering, a router automatically update filtering rules based on its route information and does not require operators’ manual change. However, uRPF, specifically strict mode, has a drawback in that it may incorrectly detect packets as spoofed, when route is asymmetric, i.e., the route from the sender and the routes to the sender are different each other. This is due to the fact that uRPF uses the local (received router’s own) route information. In this paper, we propose a method to filter using global route information. Here, global means that route information of sender routers. Generally, however, route information of sender routers’ are not available. Thus, we use public available route information provided by RouteViews project, and estimate the route information of sender routers. We verify 82% ASs can be validated using this estimation.
