Traffic Engineering Extensions to OSPF for Generalized MPLS (GMPLS) Control of Evolving G.709 OTN Networks

Traffic Engineering Extensions to OSPF for Generalized MPLS (GMPLS) Control of Evolving G.709 OTN Networks 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.
