A method for mapping a network, in accordance with the present invention,
includes providing distance measurements between tracers in the network,
determining routes along which the distance measurements are made, and
creating a system of equations which links the distance measurements
between the nodes with a sum of the delays between the nodes which
comprise the routes. Additional information is extracted about distances
of subpaths of the routes to provide additional details to a map of the
network. The additional information provides a capability of estimation
of distances between nodes without tracers.
