Abstract
A method is provided for determining the length of node-to-node links in a computer network. The method includes measuring the forwarding time for each node-to-node link in the network, eliminating queuing time from each forwarding time measurement, determining and subtracting store-forward time from each forwarding time measurement, determining and subtracting execution time from each forwarding time measurement to obtain a propagation time for a signal being transmitted on each node-to-node link and, based upon the propagation time for each node-to-node link, calculating a length of each node-to-node link. A network map may also be derived by identifying internal nodes in the network, translating each store-forward time into a hop count, constructing a connectivity map of the network including a connection map of internal nodes and superimposing the calculated link lengths onto the connectivity map to determine cable length between any internal nodes with more than two connections.
