Fri, 6 Mar 2015
A route leak is a violation of the policies between the networks involved. In this project, we obtain routing information from differecent sources and make inferences to detect possible route leaks. These potential route leaks have been further investigated on their duration, the type of violation, and the type and origin of network that caused the leak-detection.
