Robert

The optical control plane ASON/WSON/SSON for that would be the same GMPLS
control plane for IP/Optical  used today for TDM CES (circuit emulation
services) over IP/MPLS, would now also used for Routed Optical SR-MPLS
networks.

The control plane topic is orthogonal to the draft so don’t think it’s
relevant, however maybe informative references could be added.

Regards

Gyan
