Topology discovery in broadband networks

摘要

A method of operating a policy server connected to a network including a plurality of network termination devices and a plurality of CPEs (customer premises equipment) that are behind the plurality of network termination devices, the method including: polling the plurality of termination devices for data maintained by the termination devices; processing the polled data to generate topology information, the topology information identifying which CPEs are behind which termination devices; and storing the topology information in a topology data structure.
