The ITU-T G.8032/Y.1344 Ethernet Ring Protection (ERP) switching mechanism is a self-configuring
algorithm that maintains a loop-free topology while providing data path redundancy and network
scalability. ERP provides fast recovery times for Ethernet ring topologies by utilizing traditional Ethernet
MAC and bridge functions.
