  Traffic Engineering Extensions to OSPF for Generalized MPLS (GMPLS)
                 Control of Evolving G.709 OTN Networks
                 draft-ietf-ccamp-gmpls-ospf-g709v3-07

Abstract

   This document describes Open Shortest Path First - Traffic
   Engineering (OSPF-TE) routing protocol extensions to support
   Generalized MPLS (GMPLS) control of Optical Transport Networks (OTN)
   specified in ITU-T Recommendation G.709 as published in 2012.  It
   extends mechanisms defined in RFC4203.
