hi Mark,
Well this is just similar to what I am also interested.
I have actually not started working on it, but have some resources, if
possible just download and go through this paper, which speaks abt
"Toology Discovery"
Details of paper:
-----------------
Topology Discovery for Large Ethernet Networks
by
Bruce Lowekamp
David R. O.Hallaron
Thomas R. Gross
-------------------------------------------------------------
ABSTRACT
Accurate network topology information is important for both network
management and application performance prediction. Most
topology discovery research has focused on wide-area networks
and examined topology only at the IP router level, ignoring the need
for LAN topology information. Recent work has demonstrated that
bridged Ethernet topology can be determined using standard SNMP
MIBs; however, these algorithms require each bridge to learn about
all other bridges in the network. Our approach to Ethernet topology
discovery can determine the connection between a pair of the
bridges that share forwarding entries for only three hosts. This minimal
knowledge requirement significantly expands the size of the
network that can be discovered. We have implemented the new algorithm,
and it has accurately determined the topology of several
different networks using a variety of hardware and network configurations.
Our implementation requires access to only one endpoint
to perform the queries needed for topology discovery.

Waiting for our active list participants to respond.....
