Routing State Distance: A Path-based Metric For Network Analysis. Proc. ACM IMC, Boston, MA, USA, Nov. 2012. http://cs-people.bu.edu/goncag/papers/imc12-rsd.pdf The size and complexity of the millions of BGP paths in use at any time can hide important phenomena and hinder attempts to understand the path selection behavior of ASes. In this paper we introduce a new approach to analysis of the interdomain routing system designed to shed light on collective routing policies. Our approach starts by defining a new metric for ‘distance’ between prefixes, which we call routing state distance (RSD). We show that RSD has a number of properties that make it attractive for use in visualizing and analyzing the state of the BGP system.
