The work describes the creation of the original model of the RPD Module, a component of the Remote PHY Node. This model incorporates GCP/R-DEPI/R-UEPI integration, which has been implemented using cutting-edge packet processing technologies for the enhanced data transmission between CCAP Core and the cable modem via DOCSIS 4.0. The model is open-source and, therefore, does not impose limitations on various applications and improvements for hybrid fiber-coaxial networks. The developed model enhances the performance of processing data packets and improves the reliability of next-generation broadband cable telecommunication networks.
