Industrial communication networks. High availability automation networks. Media Redundancy Protocol (MRP) | Status: Superseded, Withdrawn

1 Scope The IEC 62439 series is applicable to high-availability automation networks based on the ISO/IEC/IEEE 8802‑3 (IEEE 802.3) (Ethernet) technology. This part of the IEC 62439 series specifies a recovery protocol based on a ring topology, designed to react deterministically on a single failure of an inter-switch link or switch in the network, under the control of a dedicated media redundancy manager node.
