TL;DR: This paper presents a methodology for identifying the autonomous system (or systems) responsible when a routing change is observed and propagated by BGP, and finds that it can pinpoint the origin to either a single AS or a session between two ASes in most cases.

TL;DR: A network virtualization architecture is described as a technology for enabling Internet innovation and some of its components are evaluated based on experimental results from a prototype implementation to gain insight about its viability.

TL;DR: By presenting a BGP-focused state-of-the-art treatment of the aspects that are critical for a rigorous study of this inter-domain topology, this paper demystify in this paper many "controversial" observations reported in the existing literature and illustrate the benefits and richness of new scientific approaches to measuring, modeling, and analyzing the inter- domain topology.

TL;DR: This work demonstrates that there are two limitations of prior models of the Internet: (i) they have all assumed that an Autonomous System is an atomic structure - it is not, and (ii) models have tended to oversimplify the relationships between ASes.

TL;DR: It is shown that some of the limitations of visibility given by routing and probing tools can be carefully addressed when designing an experiment, and that not seeing the reverse path taken by a probe can be partly compensated for by the methodology, called dual probing.
