Overview
This section provides details about the deployment models supported by Routed Optical Networking. It helps to understand how the solution can be applied to greenfield, brownfield, router-only, and optical-line-system-based network designs.
There is no one-size-fits-all solution for deploying a new architecture. The approach depends on the structure of the network and the goals of its owner. Therefore, it is critical to have a flexible control platform that supports a phased deployment and a smooth evolution.
Routed Optical Networking deployment
When a new IP and optical network is deployed, the hardware, together with its control architecture – including Crosswork Hierarchical Controller, Crosswork Network Controller, and Cisco Optical Network Controller, are installed from scratch. Install Crosswork Hierarchical Controller ahead of time to prepare for Routed Optical Networking deployment. This helps in planning the network using accurate data on existing services, network, and fiber assets. See Components of automation.
Third-party optical network Routed Optical Networking deployment
When routers with ZR and ZR+ optics are deployed over networks that use third-party optical devices, Crosswork Hierarchical Controller is integrated with Crosswork Network Controller and the existing DWDM optical controllers. Crosswork Hierarchical Controller creates IP links between the routers by configuring the optical path through the optical controllers and terminates those paths on the DWDM transceivers in the routers.
