High availability automation networks: PRP and HSR ring implementations

The work developed has as basis the networks/protocols described in the standard IEC 62439-3 Industrial automation networks - High availability automation networks: PRP and HSR. The similarities of both networks and a software implementation over Linux of PRP protocol have been the starting points taken for this work. A prototype of a HSR node has been developed; this prototype was proved over some virtual machines connected in a ring network as the standard states and achieved the target of seamless availability. Then it has been ported over an FPGA to validate the system in a FPGA/PC heterogeneous network.
