                       GMPLS Signaling Extensions
        for Control of Evolving G.709 Optical Transport Networks

Abstract

   ITU-T Recommendation G.709 [G709-2012] introduced new Optical channel
   Data Unit (ODU) containers (ODU0, ODU4, ODU2e, and ODUflex) and
   enhanced Optical Transport Network (OTN) flexibility.

   This document updates the ODU-related portions of RFC 4328 to provide
   extensions to GMPLS signaling to control the full set of OTN
   features, including ODU0, ODU4, ODU2e, and ODUflex.
