Internet Engineering Task Force (IETF) F. Zhang, Ed. Request for Comments: 7139 Huawei Updates: 4328 G. Zhang Category: Standards Track CATR ISSN: 2070-1721 S. Belotti Alcatel-Lucent D. Ceccarelli Ericsson K. Pithewan Infinera March 2014 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.
