Abstract
A path trace apparatus according to this invention for tracing path having specified start, middle and end points in a network comprises means for tracing a path in a forward direction from the middle point to the end point based on data representing the coupling relationship between elements constituting the network, and means for tracing a path in a reverse direction from the middle point to the start point based on the data. In tracing a path in a network by specifying three points, signal paths are traced in the forward and reverse directions with the middle point as the center, thus eliminating the wasteful tracing of paths which do not pass the middle point and thereby significantly increasing the tracing efficiency.
