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
where the SSON LSP (the Media Channel in RFC7698) use multiple
