RE: Reconstructing network topology maps

["Tenorio, Leandro" <LTenorio () intelaction com>]

Ramon,
        There are several products that do those things, one of the most
used in Telcos, most of them base on SUN or HP, is HP OpenView, it's
uses SNMP, for topology gattering, for both Level 2 and 3. It also do
system monitoring and any SNMP data GET you set it. But, at least in my
knowledge, you can't export to visio. There are other tools like
solarwids that do similar things, actualy Visio 2002 Net Architect, do
something similar.
        Hope this helps.

Subject: Reconstructing network topology maps

I am currently looking for a software that can generate (reconstruct) a
network topology from raw data obtained from live network capturing or
offline tcpdump capture files.

A co-worker told me he once saw a commercial product belonging to SUN
Microsystems on a Teleco that doe's just that but I couldn't find it
through my frantic googling today...

He said they hooked it up to a Switch of a lab network and slowly the
app reconstructed a graphical display of the network as seen from the
switch, amazing!

It was then possible to export the drawing to VISIO or see it with the
program's built-in viewer.

It mapped routers, servers, workstations, printers, computed bandwidth!
and just about every device on the net, keeping all of the information
about them (Hardware type, IP, MAC address
etc..) in an SQL-server database for future map genereation and data
recovery direct from the db.

the software parsed a variety of protocols in order to recunstruct the
network, SNMP, telnet (it parsed basic router configurations!!), BGP,
ICMP and so on...

If anybody has heard of this software (supposedly by SUN Microsystems
and built in Java) or anything remotley similar, It would be great if
you drop me a line since I am looking for such a toy for quite some
time..

Thanks,
-Ramon Szmuk
