outline

motivation: macroscopic topology study
infrastructure-relevant research questions
led us to analyze BGP data on its own
realized that routing & topology inextricably related
describe both kinds of data sets
introduce techniques for analysis of Internet `core'
graph theoretic model
combinatorial core vs giant component
dual graph
subprefix connected components
introduce metrics for analysis
indegree/outdegree characteristics
transit versus origin role
new contributions to the field of topology analysis
new granularities: BGP atoms, dual AS graph, ramified atoms
size distributions (weibull) with explanatory model (coalesence) 
reachability functions
topological resilience
