Information model for G.709 Optical Transport Networks (OTN)
draft-ietf-ccamp-otn-g709-info-model-03
Abstract
The recent revision of ITU-T recommendation G.709 [G.709-v3] has
introduced new fixed and flexible ODU containers in Optical Transport
Networks (OTNs), enabling optimized support for an increasingly
abundant service mix.
This document provides a model of information needed by the routing
and signaling process in OTNs to support Generalized Multiprotocol
Label Switching (GMPLS) control of all currently defined ODU
containers.
