Evaluation of Existing GMPLS Encoding
against G.709v3 Optical Transport Networks (OTNs)
Abstract
ITU-T recommendation G.709-2012 has introduced new fixed and flexible
Optical channel 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 OTNs.

RFC 7096 GMPLS Evaluation against G.709v3 OTNs January 2014
1. Introduction
GMPLS routing [RFC4203] [RFC5307] and signaling [RFC3473] [RFC4328]
provide the mechanisms for basic GMPLS control of Optical Transport
Networks (OTNs) based on the 2001 revision of the G.709 specification
[G.709-2001]. The 2012 revision of the G.709 specification
[G.709-2012] includes new OTN features that are not supported by
GMPLS.
This document provides an evaluation of exiting GMPLS signaling and
routing protocols against G.709 requirements. Background information
