Its been a few years since I looked at network discovery and mapping tools. Openview/et al did the job, but was always a pain to move all the boxes to the right spots on the resulting maps. Has network discovery and mapping improved for medium-scale wide area networks for ISPs (e.g. 1,000 networks, 100,000 network devices)? I've found lots of discovery tools, but intelligent mapping/layout still seems to be a problem. The usual requirements for SNMP smart discovery, interface/subnet mapping, device identification and connecting the right symbols with the right lines to all the other symbols.

www.solarwinds.net They have excellent collection of tools which is probably what you;re looking for. Windows only afaik -- Best regards, Subhi S Hashwa mailto:subhi@thebigboss.com Operations Manager Electronic Corner Limited

That's quite a "medium-scale". Is there a single entity in the world that controls 1,000 networks and 100,000 network devices? Andy --- Andy Dills Xecunet, Inc. www.xecu.net 301-682-9972 ---

Well, sure, MCI is a single company that owns that many networks and possibly network devices, but are you saying there's a single group of people within MCI who are tasked with mapping, down to the host level, across their entire network? It would seem reasonable to me that there is some hierarchy involved...European division deals with its network, etc. On Sun, 22 Jun 2003, Jonathan Crockett wrote:

What would be the value of mapping all those CPEs? Not that there isn't one, I just don't know what it is. Andy --- Andy Dills Xecunet, Inc. www.xecu.net 301-682-9972 ---

Its a bit like the fish that got away. People have varying ideas about how big is big. Its smaller than the Internet, but larger than a mom&pop network. Most americans consider themselves "middle-class," no matter what their net worth is. As far as a "single entity," obviously all large organizations have learned how to delegate responsibility. The US Military has about 3 million network devices connected to 3,000 networks. But no single person really controls all 3 million network devices. Its the organizational gaps between entities I'm interested in mapping. I want to discover and map the connections indviduals may know about, but no one realized how all the pieces were connected. So far the recommendations have included Cheops NetViz OpenView Intermapper

I'm not one to push commercial products, but I don't know of a freely available tool that does the equivalent of what Lumeta <http://www.lumeta.com> does. This being the solution based on the original work of Cheswick and Burch. This may be just the kind of thing if you need to discover unexpected or even unknown paths. John

Cheops and Cheops-ng might be useful to you. http://www.marko.net/cheops/ http://cheops-ng.sourceforge.net/ Justin
