what: new tool from CAIDA group why: (original motviation) visualization of Internet traffic and topologies is an important next step in the global evolution of the net. as a result, the cooperative association of internet data analysis (caida) is working on a new tool -- mapnet where: www.caida.org/Tools/Mapnet/Backbones how: mapnet will permit visualization of the infrastructure of multiple backbone providers simultaneously. it also allows individual isps to update and correct information about their infrastructure, either via a GUI or ascii mail in template form. (see mapnet update at www.caida.org/Tools/Mapnet/Update) the current prototype version relies on third party data (boardwatch, with some updates and clarifications) each of the commercial backbones and government provided data about federally funded r&e and mission-oriented backbones. caida staff have translated topology information provided in the last boardwatch release into lat/long specific nodes on a global map. the data are useful in a general sense, any data from a 3rd party obviously requires authentication. we recognize that much backbone-specific info is outdated or wrong and invite each provider to designate an authorized individual to periodically update their topology data. note that we include link, ISP, bandwidth, lat/long of cities, and peering information if available, as well as contact folk for the network in question. the availability of a tool like mapnet will assist with macro-level understanding of the internet, with standardizing public depiction of isps' infrastructure, and with communicating complicated peering information. (for those isp's willing to share in such an endeavor) we would appreciate any feedback: comments, constructive criticism, suggestions. please contact me or send email to brad huffaker (lead developer, mapnet) at mapnet@nlanr.net. tnx k caida kc@caida.org nlanr kc@nlanr.net
