The Cisco Routed Optical Network is a transformative architecture designed to optimize the transport of IP services by integrating optical and IP layers into a single framework. It aims to simplify network operations by eliminating redundant layers and complexities associated with traditional siloed infrastructures. By leveraging advanced technologies like 400G coherent transponders and Segment Routing, it enables service providers to achieve significant cost savings—up to 40%—while enhancing network efficiency and capacity.

The Routed Optical Network can lead to cost savings through several mechanisms. By consolidating multiple services into a single IP/MPLS network layer, it reduces the need for extensive infrastructure investments. Service providers can experience savings of up to 45% in capital expenditures and 60% in operational expenses. Additionally, the architecture minimizes the need for costly regeneration and maximizes fiber utilization, which further contributes to lowering the total cost of ownership.

Automation is a crucial element in the Routed Optical Network, as it facilitates closed-loop operations across the integrated IP and optical infrastructure. This approach allows for efficient service path computation, activation, orchestration, and optimization, which ultimately leads to shorter service lead times and improved operational efficiency. By streamlining processes and reducing manual interventions, automation helps service providers manage their networks more effectively in the face of growing traffic demands.
