SYSTEM AND METHOD FOR DISCOVERING AND VERIFYING A HYBRID FIBER-COAXIAL TOPOLOGY IN A CABLE NETWORK ENVIRONMENT

摘要

A method in an example embodiment can include polling a first cable modem in a cable network and receiving a first response message from the first cable modem identifying a downstream frequency detected by the first cable modem. The method further includes determining the downstream frequency is split between at least two fiber nodes and determining a cable modem termination system (CMTS) service group topology, where the topology includes the at least two fiber nodes. In specific embodiments, determining that the downstream frequency is split is based on at least the first response message from the first cable modem and a second response message from a second cable modem. In more specific embodiments, the method includes constructing a hybrid fiber-coaxial (HFC) topology map of the cable network based on at least the first and second response messages, where the HFC topology map indicates the CMTS service group topology.
