Evaluation of existing GMPLS encoding against G.709v3 Optical Transport
                             Networks (OTN)
                draft-ietf-ccamp-otn-g709-info-model-10

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.

Internet-Draft    GMPLS evaluation against G.709v3 OTN         July 2013

1.  Introduction

   GMPLS routing and signaling, as defined by [RFC4203], [RFC3473] and
   [RFC4328], provides the mechanisms for basic GMPLS control of OTN
   networks based on the 2001 revision of the G.709 specification.  The
   2012 revision of the G.709 specification, [G.709-2012], includes new
