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.
