       Applicability of GMPLS for B100G Optical Transport Network
           draft-ietf-ccamp-gmpls-otn-b100g-applicability-01

Abstract

   This document examines the applicability of using current existing
   GMPLS routing and signaling to set up ODUk/ODUflex over ODUCn link,
   as a result of the support of OTU/ODU links with rates larger than
   100G in the 2016 version of G.709.
