Information model for G.709 Optical Transport Networks (OTN)

The recent revision of ITU-T recommendation G.709 [G.709-v3] has introduced new fixed and flexible ODU containers in Optical Transport Networks (OTNs), enabling optimized support for an increasingly abundant service mix. This document provides a model of information needed by the routing process in OTNs to support Generalized Multiprotocol Label Switching (GMPLS) control of all currently defined ODU containers both at sub- lambdas and lambda level granularity.
