  GMPLS Signalling Extensions for control of B100G OTUCn/ODUCn Network
                draft-zihc-ccamp-otn-b100g-signalling-00

Abstract

   This document provides extensions to GMPLS signalling to control the
   B100G OTUCn/ODUCn Network, as a result of the introduction of new
   beyond 100G OTUCn/ODUCn signals in ITU-T Recommendation G.709
   [G.709-2016].

1.  Introduction

   The 2016 version of G.709 [G.709-2016] introduces support for higher
   rate OTU and ODU signals, termed OTUCn and ODUCn (which have a
   nominal rate of 100n Gbps).  The newly introduced OTUCn and ODUCn
   represent a very powerful extension to the OTN capabilities, and one
   which naturally scales to transport any newer clients with bit rates
   in excess of 100G, as they are introduced.

   B100G framework document [I-D.zih-ccamp-otn-b100g-fwk] provides a
   framework to allow the development of protocol extensions to support
   GMPLS control of OTN as specified in [G.709-2016].  Based on this
   framework, this document provide Resource Reservation Protocol -
   Traffic Engineering (RSVP-TE) extensions to support control of OTUCn/
   ODUCn introduced in [G.709-2016].

   Note: the RSVP-TE signalling extensions in this document will try to
   reuse the extensions defined in RFC4328 [RFC4328] and RFC7139
