The Research on Ethernet Ring Protection Switching

Abstract:

TU-T has recommended a standardized scheme for achieving sub-50ms service protection in ring topologies through Ethernet Ring Protection Switching (ERPS) specified in G.8032 recommendation^[. ERPS provides a means to reliably achieve carrier-class network requirements for Ethernet topologies forming a closed loop. This article outlines an Ethernet ring protection switching mechanism and explains how its automatic protection switching (APS) protocol works. In addition, this article illustrates a sample scenario with failure and recovery.
