    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.},
