In graph theory, what is the difference between a trail and a path. You seem to have misunderstood something, probably the definitions in the book. If the graph has weights on its edges, then its weighted diameter measures path length by the sum of the edge weights along a path, while the unweighted diameter measures path length by the number of edges.
