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that may be invalid or out of date (Mapnet Update).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.
