The following description is the project description from the NSF proposal. There is no equivalent available for the Research and Education community.
Some maps are available on each networks web site or directly from each network's engineering team.
Unfortunately maps are not available for many networks of interest and maps that are available are presented in an inconsistent format and scope, and in fact are sometimes out of date. Moreover, network maps do not use standard symbols, making comparisons among maps difficult and confusing. Although the JETnet Peering map is available upon request, it is not currently available on the web. All of the problems described above also apply to international research and education networks. For researchers in the United States who might not even be aware that non-US networks exist, much less what they are called, gathering information on these networks is even more difficult.
