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 RFC 7698.  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

   Generalised Multiprotocol Label Switched (GMPLS) is widely used in
   Wavelength Switched Optical Network (WSON) to support the optical
   circuits set-up through the signalling between Core Nodes and Edge
   Nodes.  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
   wants do address the use cases where the SSON LSP (the Media Channel
   in RFC7698) carries multiple carrier (OTSi) containing same Payload.
   The set of the carriers can be seen as single Logical circuit.  This
