Internet topology at the router and autonomous system level
We present a statistical analysis of different metrics characterizing the topological properties of Internet maps, collected at two different resolution scales: the router and the autonomous system level. The metrics we consider allow us to confirm the presence of scale-free signatures in several statistical distributions, as well as to show in a quantitative way the hierarchical nature of the ...
متن کاملAdaptive Topology Discovery in Hybrid Wireless Networks
Wireless networks in home, office and sensor applications consist of nodes with low mobility. Most of these networks have at least a few powerful machines additionally connected by a wireline network. Topology information of the wireless network at these powerful nodes can be used to control transmission power, avoid congestion, compute routing tables, discover resources, and to gather data. In...
متن کاملAnalyzing and Modeling Router-Level Internet Topology
Measurement studies on the Internet topology show that connectivities of nodes exhibit power–law attribute, but it is apparent that only the degree distribution does not determine the network structure, and especially true when we study the network–related control like routing control. In this paper, we first reveal structures of the router–level topologies using the working ISP networks, which...

متن کاملInferring AS-level Internet Topology from Router-Level Path Traces
A number of recent studies characterize AS-level topology of the Internet by exploiting connectivity information contained in BGP routing tables. In this paper, we present an alternative method for discovering AS connectivity by inferring individual AS connections from the Internet's router-level topology. This methodology has several advantages over using BGP routing tables. First, it allows u...
