IEC 62439-2:2010 is applicable to high-availability automation networks based on the ISO/IEC 8802-3 (IEEE 802.3) (Ethernet) technology. It 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. It cancels and replaces IEC 62439 published in 2008 and constitutes a technical revision. It includes the following significant technical changes with respect to IEC 62439 (2008):


- adding a calculation method for RSTP (rapid spanning tree protocol, IEEE 802.1Q),


- adding two new redundancy protocols: HSR (High-availability Seamless Redundancy) and DRP (Distributed Redundancy Protocol),


- moving former Clauses 1 to 4 (introduction, definitions, general aspects) and the Annexes (taxonomy, availability calculation) to IEC 62439-1, which serves now as a base for the other documents,


- moving Clause 5 (MRP) to IEC 62439-2 with minor editorial changes,


- moving Clause 6 (PRP) was to IEC 62439-3 with minor editorial changes,


- moving Clause 7 (CRP) was to IEC 62439-4 with minor editorial changes, and


- moving Clause 8 (BRP) was to IEC 62439-5 with minor editorial changes,


- adding a method to calculate the maximum recovery time of RSTP in a restricted configuration (ring) to IEC 62439-1 as Clause 8,


- adding specifications of the HSR (High-availability Seamless Redundancy) protocol, which shares the principles of PRP to IEC 62439-3 as Clause 5, and


- introducing the DRP protocol as IEC 62439-6.
