Abstract
A system for determining a topology associated with a network such as an enterprise network. The system includes a data collection agent 204 configured to (a) identify a first set of routers from among a larger, second set of routers in an enterprise network, (b) contact each of the routers in the first set of routers but not each of the other routers in the second set of routers, and (c) load network information maintained by at least some of the contacted routers in the first set of routers. The loaded network information can then be used to form a network or routing topology of the enterprise network.
