Description

IEC 62439-2 Ed. 3.0 b – Industrial communication networks – High availability automation networks – Part 2: Media Redundancy Protocol (MRP)

The IEC 62439 series is applicable to high-availability automation networks based on the ISO/IEC/IEEE 8802-3 (IEEE Std 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.
