  Traffic Engineering Extensions to OSPF for Generalized MPLS (GMPLS)
                 Control of Evolving G.709 OTN Networks
                 draft-ietf-ccamp-gmpls-ospf-g709v3-02

Abstract

   The recent revision of ITU-T Recommendation G.709 [G709-V3] has
   introduced new fixed and flexible ODU containers, enabling optimized
   support for an increasingly abundant service mix.

   This document describes OSPF routing protocol extensions to support
   Generalized MPLS (GMPLS) control of all currently defined ODU
   containers, in support of both sub-lambda and lambda level routing
   granularity.
