Ethernet Ring Protection Switching

In network operator infrastructures around the globe, cost-effective optical Ethernet services are increasingly replacing classic SONET/SDH technology in the metro/access network layers and beyond. Truly substituting SONET or Ethernet, however, demands replicating the resilient ring topologies to reduce the number of links required in multipoint configurations while also matching the sub 50ms automatic protection switching timeframes required of the attached devices without an underlying SONET/SDN transport layer in place.

Supporting single ring (G.8032v1) and multi-ring (G.8032v2) topologies, Ethernet Ring Protection Switching (ERPS), ratified within the ITU-T, specifies sub 50ms protection switching and a protocol for Ethernet layer rings. Contact Metaswitch to learn more about out ERPS solution.
