TopDNS: Experiences Building Internet-Based Topologies with GNP

Building realistic Internet topologies is an important step towards predicting the behavior of new distributed applications and protocols.We are creating topologies that predict the distances between identifiable nodes in the Internet as it is today.These nodes are not anonymous average Internet nodes, but are known by name and network address.We are using a landmark and network coordinate based approach and evaluate the characteristics of the topologies found.We provide hints, how to select important parameters for such topology generators.
