Abstract
ITU-T Recommendation G.709 [G709-2012] has introduced new Optical
channel Data Unit (ODU) containers (ODU0, ODU4, ODU2e and ODUflex)

and enhanced Optical Transport Networking (OTN) flexibility.
This document updates RFC4328 to provide the extensions to the
Generalized Multi-Protocol Label Switching (GMPLS) signaling to
control the evolving OTN addressing ODUk multiplexing and new
features including ODU0, ODU4, ODU2e and ODUflex.
