Abstract

The importance of an autonomous system is typically derived by its economic relevance, in Internet terms measured by the number of customer ASes it provides with connectivity. Such simple business relationship does not hold anymore. In this paper, we analyze the importance of peer-to-peer links between BGP peers. We show that settlement-free peering may change the global rank of an AS by three orders of magnitude.
