Advances in Packet Optical Transport in Optical Networking and Broadband Transmission

The ring variant of 50 ms is standardized by ITU-T in the G.8032 (Ethernet ring protection scheme) standard. Ethernet ring protection switching (ERPS) offers the concept of ringlets, where a single physical ring can be partitioned into multiple logical ringlets based on the Ethernet virtual local area network (VLAN) tags. This provides more flexibility as different ring-lets can be configured with different priority. An extension of ERPS, called Open ERPS, can be used to provide dual homing. In this case, for example, two routers can be interconnected in an open ring fashion. In case of a failure, an ERPS-enabled node simply starts sending traffic in the other direction. Thus, one of the routers is reachable in case of a single failure.
The Ethernet Advantage in Networking

The industry standard for implementing Ethernet ring networks is ITU-T Recommendation G.8032, Ethernet Ring Protection Switching (ERPS) [ITUTG8032]. Some vendor-based (proprietary) techniques for creating Ethernet rings include Cisco’s Resilient Ethernet Protocol (REP) [CISCDOC116384], [CISCREPGUID], [CISCREPWP07], Extreme Networks’ Ethernet Automatic Protection Switching (EAPS) [RFC3619], 3Com and Huawei (H3C) Rapid Ring Protection Protocol (RRPP) [H3CRRPP], Allied Telesis’ Ethernet Protection Switching Ring (EPSRing™) [ALLIEDTEPSR], Brocade’s Metro Ring Protocol (MRP) [BRODMRP], and Force10 Redundant Ring Protocol (FRRP) [DELLFRRP].

Performance associated with the use of ERPs can be reflected in better access to information, greater reliability, the elimination of redundant data in operations, the reduction of time cycles, greater efficiency and, consequently, decreases in costs. In general, processes supported by ERP optimize the strategic management of organizations (Zhang et al. 2003; Hongyi, Wenbin, and Lam 2015; Matende and Ogao 2013).
