Hi, When running many traceroutes that traverse the same "anonymous" hop between two known hosts, zenmap creates a new node in the graph for each traceroute. This introduces a lot of unnecessary clutter in the graph. 200 traceroutes passing 2 (physical) anonymous devices currently generates 400 nodes in the topology graph. Sure, it might be a new physical anonymous device each time, but it most likely isn't. Even if it is, I don't think it makes sense to represent them as two distinct nodes (since there is no way to tell them apart). I suggest combining nodes in the graph that represent anonymous hops between two known devices. / anon_1 \ ..-> ip_a ip_b -> .. => .. -> ip_a -> anon_1 -> ip_b -> .. \ anon_2 / Here is a patch implementing this behavior: http://www.4zm.org/files/2011/integration.py.diff
I think I see what this is supposed to be doing, but it didn't work when I tried it. Here's an XML traceroute file and a graphic of what I'm seeing. David Fifield
