The OpenROADM API enables software-defined control and management of open networks through three models: device, network, and service. The device model is used as a vendor-neutral framework for managing network elements, while the network and service models offer a generic and vendor-independent approach to managing networks and services.

Once these models are implemented in the network elements and/or the SDN network controller, they provide a standardized and unified management interface, promoting an environment that facilitates interoperability, reduces vendor lock-in, and ultimately decreases the total cost of network ownership.

With the OpenROADM API, network operators gain the flexibility to mix and match components from multiple vendors and manage them through a common interface, enhancing the openness and agility of their optical networks. By embracing open standards and promoting interoperability, the OpenROADM community is driving innovation and transformation in the optical networking industry.
