What is Mapnet used for?
- Mapnet is a tool used for visualizing the geographic toplogy of multiple network infrastructures.
What is the status of Mapnet?
- Mapnet is a past CAIDA project and is not currently funded.
Who maintains Mapnet?
- Because Mapnet is not currently a funded project, it is currently not maintained nor supported but is made available for public use.
how you can help
Network administrators: You can help NLANR/CAIDA provide more accurate visualizations of the Internet by putting latitude/longitude information into your DNS configuration. Here's how.
Visualization of the Internet beyond the purview of a single provider has become challenging task that has received little attention from the research community. Commercial Internet service providers grow increasingly hesitant to voluntarily publish topology or peering information about their networks, and those that do so use no standard format, leading to the problem that any existing maps are fairly incomparable with each other.
At the same time, the evolution of cooperative research networks, currently framed by the NSF, new connections to the vBNS, and cooperating U.S. federal agencies, has given rise the the desire to be able to share performance information across infrastructures, perhaps even commerical ones.
We have developed a tool for visualizing the infrastructure of multiple backbone providers simultaneously (Mapnet), and for updating and correcting information that may be invalid or out of date (Mapnet Update). The tool's accuracy unmitigatably relies on the cooperation of providers in keeping the information accurate. We are also developing a module that will allow one to request performance or routing information across arbitrary points of the infrastructure amenable to measurement.
