The paper "Topological Implications of Cascading Interdomain Bilateral Traffic Agreements", co-authored by Vitor Jesus, Rui L Aguiar, Peter Steenkiste, has been acepted for publication in IEEE Journal On Selected Areas In Communications, Special Issue on "Measurement of Internet Topologies", to be published in October 2011.
This paper discusses the topological implications of cascading interdomain SLAs, between Autonomous Systems, using real-world assumptions suggesting that the current Internet topology, still mainly hierarchical, is strongly influenced by business practices and not only technical considerations.
