Routed Optical Networking has these benefits.

• Cost Savings: Routed Optical Networking reduces the network's total cost of ownership. Routed Optical networks make the most efficient use of high capacity routers and DWDM optical infrastructure. The routers' high-capacity switching allows networks to achieve denser interconnection and move traffic protection to the IP layer. Routed Optical Networking saves costs by converging service layers, simplifying the DWDM optical system, and using industry-standard ZR and ZR+ pluggable digital coherent optics. Elimination of multiple layers reduces power usage and hardware footprint. End-to-end multi-layer automation enables better utilization of network capacity.

• Simplification: Using Agile Services Networking technologies like Segment Routing, EVPN. and Routed Optical Networking simplifies networks from the base infrastructure layer to the services layer. Using Circuit-Style Segment Routing and Private Line Emulation, Routed Optical Networking allows providers to converge services while maintaining or exceeding existing private line service SLAs. This convergence leads to simplified planning, design, activation, management, and troubleshooting.

• Automation: Automation enhances resiliency, improves failure detection, and simplifies repair processes. Enhanced multi-layer visibility and root cause analysis allow network operators to quickly discover and remedy faults. Troubleshooting is enhanced with rich network telemetry at each layer.

• Optimize Capacity: Routed Optical Networking uses the IP layer's capability to statistically multiplex network traffic at the packet level. Statistical multiplexing efficiently carries network traffic, adapting to instantaneous traffic demands and avoiding idle link capacity. Routed Optical Networking networks utilize fiber capacity to its fullest by intelligently utilizing capacity at the IP layer instead of wasting DWDM resources with unnecessary bypass circuits.
