The invention broadly comprises a computer-based method for presenting
information regarding network performance and topology. The steps of the
method include: displaying a first plurality of nodes in the network;
displaying edges associated with the first plurality of nodes; and,
displaying latency associated with the edges. The preceding steps, and
those that follow, are performed by at least one general-purpose computer
specially programmed to perform these steps. In some aspects, the method
selects the first plurality of nodes. In some aspects, the network
comprises a plurality of ISPs with respective pluralities of nodes and
the respective pluralities of nodes comprises the first plurality of
nodes. In some aspects, displaying a first plurality of nodes, edges, and
latency is independent of cooperation from the plurality of ISPs. In some
aspects, the method gathers information regarding the first plurality of
nodes from vantage points outside the first plurality of nodes.
