Hi Etienne,
Below is our (Cisco) definition of the Routed Optical Network. The
goal, metro or long haul or subsea, is to reduce the number of control
planes. By migration TDM traffic using CEM or PLE to the IP layer, you
eliminate the OTN control plane and management. Eventually, when
standards are settled the ultimate goal is to have a single
control plane for the network. I'm not trying to be a commercial here,
but you can read more in the resources section on this page:

Routed optical networking, is an architecture that delivers improved
operational efficiencies and simplicity. The solution works by merging
IP and private line services onto a single layer where all the
switching is done at Layer 3. Routers are connected with standardized
400G ZR/ZR+ coherent pluggable optics.
With a single service layer based upon IP, flexible management tools
can leverage telemetry and model-driven programmability to streamline
lifecycle operations. This simplified architecture integrates open
data models and standard APIs, enabling a provider to focus on
automation initiatives for a simpler topology.
To be honest, I've been hearing about this since as long as I can
remember. IPoDWDM was another attempt at trying to make the above a reality.
But for some reason, operators prefer to keep these networks separate,
and many customers, especially very large ones, prefer to bypass routers
for their Transport services.
I think the effort will be appreciated, but if history is anything to go
by, vendors are going to struggle to strip operators and customers away
from some degree of separation.
Mark.
