This project seeks to address a study of protocols for redundant and real-time industrial Ethernet networks and its implementation in high-capacity integrated electronic FPGA devices. The newly defined standards to meet the real-time requirements and redundancy are related to communication protocols: the PTP (Precision Time Protocol), PRP (Parallel Redundancy Protocol) and HSR (High Availability seamless redundancy protocol). The implementation of these protocols far from being a solved problem is a problem with many fronts derived especially from specifically designed time adjustment hardware and from the redundant transmission circuits with different latencies.
