Industrial communication networks - High availability automation networks - Part 2: Media Redundancy Protocol (MRP)
Abstract
The IEC 62439 series is applicable to high-availability automation networks based on the ISO/IEC/IEEE 8802–3 (IEEE Std 802.3–2018) (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.
