Zero Touch photonic solutions require a carefully designed control plane to cope with physical impairments
and the need for 3R regeneration. GMPLS providing the flexibility to add regeneration where needed, extends
the reach of WDM network domains beyond the physical limits of pure wavelength switching.
The benefits of restoration in meshed compared to ring based transmission
networks are widely accepted and recognized. This article goes a step
further and analyzes the benefits of a collaboration between an IP/MPLS and optical restoration. The underlying principle is based on managed control planes and provides substantial cost savings compared to unrelated restoration mechanisms.
