• An Atlas of Cyberspace – Conceptual Maps of Cyberspaces (Cybermaps)
  http://www.cybergeography.org/atlas/atlas.html
  “.... visualise and comprehend the new digital landscapes beyond our computer screen, in the wires of the global communications networks and vast online information resources.
  The cybermaps, like maps of the real-world, help us navigate the new information landscapes, as well being objects of aesthetic interest. They have been created by 'cyber-explorers' of many different disciplines, and from all corners of the world
  ..... Atlas of maps and graphic representations of the geographies of the new electronic territories of the Internet, the World-Wide Web and other emerging Cyberspaces”.
  • Traceroute topology maps
    http://www.cybergeography.org/atlas/routes.html
    exploring and mapping the structure of the global Internet by recording all the "hops" (routers) along the different tracing Paths Through the Internet
  • Topology Maps of Elements of Cyberspace to show connectivity and traffic flows
    http://www.cybergeography.org/atlas/topology.html
  • Maps of Internet Service Provider (ISP) and Internet Backbone Networks http://www.cybergeography.org/atlas/isp_maps.html
    “Atlas presents here a sample of some of the best network topology maps created by Internet Service Providers (ISPs) and Internet backbone operators. The maps are often created for promotional purposes to demonstrate the large bandwidth and good connections available”.
    
• Caida is an organization that focuses on Internet topology discovery and monitoring. The tools they developed are:
  
  • Mapnet - Java applet that does geographically based macroscopic Internet infrastructure visualization. The data is introduced manually.
  • Otter - Java based general purpose topology visualization tool. I does not structure the network hierarchically, therefore it can be used only for viewing networks with a small number of nodes.
  • Skitter - is their discovery tool which base on traceroute and ping. Based on active probing of the network, it discovers network connectivity (topology), measures round trip time and record dynamic changes of topologies.
    
    For backbone topology visualization they use some graph layout code written by Bill Cheswick from Bell Labs and Hal Burch from CMU.
    
• MIDS Matrix Information and Directory Services is a company that claims to be the oldest in Internet analysis. They have products that provide visualization of the Internet geography :
  • MatrixIQ - a program which produces a comprehensive consistent view of the Internet and specific ISPs. They do not sell the program, nor do they have intention to open the source code.
  • Internet Weather Report - a free sampler of some partial views of the latency statistics in geographical form. Available online for free.
  • Matrix Maps Quarterly - a research publication which contains maps of the Internet worldwide by region.
    
• Mercator
  • a program that infers, using a variety of heuristics, the router-level connectivity of the Internet. Mercator requires no input. The heuristics that it uses are described in the paper

Europe's leading Internet exchange points, which connect the networks of Internet service providers (ISPs) to permit the exchange of Internet traffic, have set up the European Internet Exchange (Euro-IX).
