approach, although HSR functions primarily as a protocol for creating media redundancy while PRP creates network redundancy. Compared with PRP, HSR makes best usage of one network and it obviously saves huge cost for the construction of the whole system.

HSR High-availability Seamless Redundancy HSR provides zero recovery time in case of failure of one component. It is suited for applications that demand high availability and very short reaction time. Such applications are protection for electrical substation automation and controllers for synchronized drives. For such applications, the recovery time of commonly used protocols like the Rapid Spanning Tree Protocol is not acceptable. In HSR architecture, duplicate packets are sent in opposite directions on the ring.
