Scope

"This Recommendation defines the automatic protection switching (APS) protocol and protection switching mechanisms for ETH layer Ethernet ring topologies. The protection protocol defined in this Recommendation enables protected point-to-point@ point-to-multipoint and multipoint-tomultipoint connectivity within the ring or interconnected rings@ called ""multi-ring/ladder network"" topology. The ETH layer ring maps to physical layer ring structure. Protection schemes for the other layers@ including ETY layer@ are out of scope of this Recommendation."
