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
