NetRadar is a tool for analyzing
network topology for congestion problems. It is targeted mainly at
networking experts, but can be used by anyone with a network connection.
NetRadar produces graphs of your network connection, shown
below, which can be analyzed for things like redudandant or missing
topology, congestion problems, and similar related ideas. NetRadar is
based on a research project called RouteTree theory, which
makes traceroute and ping data reliable enough for medium-level network
analysis.
