Evaluation of existing GMPLS encoding against G.709v3 Optical Transport
                             Networks (OTN)
                draft-ietf-ccamp-otn-g709-info-model-11

Abstract

   ITU-T recommendation G.709 [G.709-2012] has introduced new fixed and
   flexible Optical Data Unit (ODU) containers in Optical Transport
   Networks (OTNs).

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