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 and signaling process in OTNs to support Generalized Multiprotocol Label Switching (GMPLS) control of all currently defined ODU containers.
