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.

1. Introduction
GMPLS[RFC3945] extends MPLS to include Layer-2 Switching (L2SC),
Time-Division Multiplexing (e.g., SONET/SDH, PDH, and OTN),
Wavelength (OCh, Lambdas) Switching and Spatial Switching (e.g.,
