ERPS (Ethernet Ring Protection Switching), sometimes referred to as G.8032 and defined in ITU-T G.8032, provides redundant path technology at the Ethernet layer with very low failover times. As stated in the name, the technology uses Ethernet switches to create a highly reliable and stable ring topology from which a robust network can be built. The technology permits the incorporation of QoS (Quality of Service) which allows network designers to comply with SLAs (Service Level Agreements) indicative of the service provider industry.
