      Information model for G.709 Optical Transport Networks (OTN)
                draft-ietf-ccamp-otn-g709-info-model-04

Abstract

   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.
