Topology Project
The exponential growth of the number of Internet hosts has been well
documented in the trade press. The research community, however, has
not seen many systematic empirical studies of how the Internet
topology evolves over time and in space. Most recently, the authors
of [FFF99] report on several power-law relationships observed
on Autonomous Systems' (AS) connectivity degree, degree frequencies,
and the neighborhood size within any given hop count from an AS. This
pioneering work represents a first important step toward a better
understanding of the dynamic nature of Internet topology, a topic we
explore further in this project.
This project is supported in part by NSF Grant No. ANI-0082287, by
ONR Grant No. N000140110617, and by AT&T Research.
