1. A cloud-based Data-Over-Cable Service Interface Specification (DOCSIS) time protocol (DTP) calibration method, comprising:
receiving, at a DTP calibration platform from a cable modem termination system (CMTS), a request including a DTP calibration testing setup defining (a) a network architecture and (b) hardware and firmware configuration of DTP capable components of a DOCSIS network;
retrieving, from the DTP calibration platform and based on the DTP calibration testing setup, associated DTP calibration data that includes an additional time adjustment y for calibrating DTP between the CMTS and a cable modem (CM) of the DOCSIS network; and
sending the associated DTP calibration data to the CMTS.
