- The Flattening Internet Topology: Natural Evolution, Unsightly Barnacles or Contrived Collapse?
- This paper collects and analyzes traceroute measurements to show that large content providers (e.g., Google, Microsoft, Yahoo!) are deploying their own wide-area networks, bringing their networks closer to users, and bypassing Tier-1 ISPs on many paths. This trend, should it continue and be adopted by more content providers, could flatten...

- Why OLPC mesh wireless networking won't work
- One of the touted features of the $200 OLPC laptop is the peer-to-peer mesh topology networking feature that can theoretically bring an Internet infrastructure where there is no network infrastructure. The problem is that peer-to-peer wireless LAN mesh topology sounds better than it actually works and there's a good reason...

- Internet maps are blooming
- It is important to understand network topology to predict its performance and its resilience to attacks. This is why computer scientists at UC San Diego have developed new algorithms which create Internet maps. Their maps -- looking like digital dandelions -- show Internet nodes and their linkages. But they are...

- Self-Forming Network Management Topologies in the Madeira Management System
- This paper describes a novel approach to network management topologies where multiple customized topologies are self-configured, self-optimized, and maintained automatically by the underlying network of elements. An implementation of these self-forming management topologies as developed in the Celtic European research project Madeira is described. The self-forming topologies use peer-to-peer communication...
