series is applicable to high-availability automation networks based on the Ethernet technology.

This document:

• - specifies PRP and HSR as two related 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;
• - specifies the operation of the precision time protocol (PTP) in networks that implement the two redundancy protocols (Annex A);
• - specifies PTP profiles with performance suitable for power utilty automation (Annex B) and industrial automation (Annex C);
• - includes for better understanding a tutorial (Annex D) on the PTP features effectively used in high-availability automation networks;
• - includes a management information base for PTP (Annex E);
• - defines a conformance test suite for the above protocols (Annex F)
