Abstract

   This memo defines the signaling extensions for managing Spectrum
   Switched Optical Network (SSON) parameters shared between the Client
   and the Network and inside the Network in accordance to the model
   described in [RFC7698].  The extensions are in accordance and
   extending the parameters defined in ITU-T Recommendation
   G.694.1.[ITU.G694.1] and its extensions and G.872.[ITU.G872].

1.  Introduction

   Generalized Multiprotocol Label Switching (GMPLS) is widely used in
   Wavelength Switched Optical Network (WSON) to support the optical
   circuit set-up through the signalling between Core Nodes and Edge
   Nodes (reusing terminology from [RFC4208.  This extension addresses
   the use cases described by [RFC7698] Ch.3.3 and supports the
   information, needed in Spectrum Switched Optical Network (SSON), to
   signal a Media Channel and the associated carriers set request.  The
   new set of parameters is related to the Media Channel and the
   carrier(s) routed with it and keep the backward compatibility with
   the WSON signalling.  In particular this memo addresses the use cases
