    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

    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.
