Thanks for your response to my questions. Please see slides 33-36 from this presentation: http://www.antd.nist.gov/~ksriram/BGP_Security_Analysis_NIST_Study.pdf We derived these statistics and plots using AS-level peering topology measurement data from Lixia's team at UCLA (December 2005). This is a good starting point, but in order to fully quantify your proposal, a distribution of ratio of prefixes (RIB entries) that point to the same peer (per BGP router) is needed. Sriram K.
