Media Redundancy Protocol (MRP) is supported “all-in-hardware”

Media Redundancy Protocol (MRP) is a data network protocol standardized by the International Electrotechnical Commission as IEC 62439-2. MRP allows rings of Ethernet switches to overcome any single failure with recovery time much faster than achievable with traditional alternatives like Spanning Tree Protocol. However, it is not able to offer zero-delay recovery time like PRP or HSR. However, it is suitable to most Industrial Ethernet applications and it is quite popular in some sectors.

SoC-e Media Redundancy Protocol (MRP) switch IP for FPGAs supports the role of client (Media Redundancy Client – MRC) or manager (Media Redundancy Manager – MRM). These mode of operation are fully implemented on hardware, and there is no need for MRP software stack.
