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.
