Abstract
The locations of nodes in a network are determined relative to the location of monitoring devices that collect trace information on the network. By appropriate sorting, filtering, and characterizing the trace information, nodes are identified as being local to or remote from each monitoring device that detects traffic to or from the node. If the trace information is insufficient to determine the relative location of a node, the node is identified as such. By identifying the nodes whose locations can be determined automatically by this analysis of the trace information, the number of nodes whose locations must be determined by more costly manual methods can be substantially reduced.
