The IEC 62439 series is applicable to high-availability automation networks based on the Ethernet technology.
This part of IEC 62439 specifies two redundancy protocols designed to provide seamless recovery in case of single failure of an inter-bridge link or bridge in the network, which are based on the same scheme: parallel transmission of duplicated information.
