Evaluation of existing GMPLS encoding against G.709v3 Optical Transport
                             Networks (OTN)
                draft-ietf-ccamp-otn-g709-info-model-05

Abstract

   The recent revision of ITU-T recommendation G.709 [G.709-2012] has
   introduced new fixed and flexible Optical Data Unit (ODU) containers
   in Optical Transport Networks (OTNs), enabling optimized support for
   an increasingly abundant service mix.

   This document provides an evaluation of existing Generalized
   Multiprotocol Label Switching (GMPLS) routing and signaling methods
   against the G.709-2012 OTN networks.
