• As autonomous systems tend to forward packets along the path with minimal routing cost, Internet routes are unevenly distributed on physical links. Links which a large number of routes go through are called routing bottlenecks. Flooding such routing bottlenecks can degrade or even cut off the network connectivity in a large area, making them a serious vulnerability of the Internet. In this paper, we study the characteristics of inter-domain routing bottlenecks and point out that they can be further aggravated by manipulating BGP updates to launch prefix hijackings. We first simulate large quantities of AS-level routing paths to illustrate the pervasiveness of inter-domain routing bottlenecks, as well as their direction, topological location, distance and concentration. Then, we propose a method for measuring and aggravating inter-domain bottlenecks of some AS, such that link flooding on them can be effectively amplified in a stealthy way. Moreover, adversary can adjust the specific method according to its purpose of malicious behaviour. At last, we discuss how inter-domain routing bottlenecks may be affected as the Internet evolves, where we witness the new, or wider, deployment of some routing related mechanisms.
