BGP Route Leaks Analysis

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.

Thu, 31 Jul 2014
The Internet has been growing rapidly for many years. A logical consequence of the growth trend is the increase in effort to discover reachability and routing information of all the networks. The project investigates the different components which together form the actual update message signal and tries to find a reason behind the growth factor.
