Abstract:
1. A method comprising: polling a first cable modem in a cable network; receiving a first response message from the first cable modem identifying a downstream frequency detected by the first cable modem; determining the downstream frequency is split between at least two fiber nodes, wherein the determining 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; determining a cable modem termination system (CMTS) service group topology, wherein the CMTS service group topology includes the at least two fiber nodes; constructing a hybrid fiber-coaxial (HFC) topology map of the cable network based on at least the first and second response messages, wherein the HFC topology map indicates the CMTS service group topology; providing a MAC domain descriptor (MDD) message to the first cable modem after the HFC topology map is constructed; and registering the first cable modem in accordance with Data-Over-Cable Service Interface Specifications 3.0 (DOCSIS 3.0), wherein the HFC topology map indicates a MAC domain cable modem service group topology associated with the cable modem.
