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
memo can be considered as the extension of [RFC7792]. The contents
