Characterizing and Mitigating Inter-domain Policy Violations in Overlay Routes

— The Internet is a complex structure arising from the interconnection of numerous autonomous systems (AS), each exercising its own administrative policies to reflect the commercial agreements behind the interconnection. However, routing in service overlay networks is quite capable of violating these policies to its advantage. To prevent these violations, we see an impending drive in the current Internet to detect and filter overlay traffic. In this paper, we first present results from a case study overlay network, constructed on top of Planetlab, that helps us gain insights into the frequency and characteristics of the different inter-domain policy violations. We further investigate the impact of two types of overlay traffic filtering that aim to prevent these routing policy violations: blind filtering and policyaware filtering. We show that such filtering can be detrimental to the performance of overlay routing. We next consider two approaches that allow the overlay networ...
