How does Cisco NSO model changes to individual devices?

Cisco NSO (Network Services Orchestrator) utilizes Network Element Drivers (NEDs) to manage interactions and model changes to individual network devices. NEDs act as a bridge between NSO and a variety of network devices, enabling NSO to understand and communicate with the specific configuration and operational requirements of each device.

The role of NEDs is crucial as they translate NSO's service models into commands and configurations that are appropriate for individual devices. This means that when a change is made to a service in NSO, the NED is responsible for converting that change into the proper format for the target device, ensuring compatibility and correctness in the process.

By leveraging NEDs, Cisco NSO can effectively manage a multi-vendor environment, allowing for a consistent command and control interface regardless of the underlying technology being used. This architecture allows network administrators to automate and orchestrate configuration changes across diverse network devices seamlessly, maintaining accurate modeling of their network environments.
