Recommendation ITU-T G.808.2 defines the generic functional models, characteristics and processes associated with various ring protection schemes for connection oriented networks;e.g.,optical transport networks (OTNs), synchronous digital hierarchy (SDH) networks. It also defines the objectives and applications for these schemes. The protection scheme described in this Recommendation is shared ring protection.Generic functional models, characteristics and processes for linear protection and interconnected subnetwork protection schemes are defined in other Recommendations.
