The core functionality of Cisco NSO is managed by which component?

The core functionality of Cisco NSO is managed by the Cisco NSO Core Engine, which acts as the central component facilitating the orchestration and management of network services. This engine is responsible for coordinating the various tasks and processes that involve service provisioning and lifecycle management. It provides abstraction from the underlying network devices and technologies, allowing for consistent service delivery across different environments.

The Cisco NSO Core Engine integrates with various components, orchestrating interactions with devices and services while ensuring the implementation of business logic processes. It supports the service model, executing service requests, and managing device configurations based on defined policies. Moreover, the engine operates on data models that describe network services and configurations, which enhances its ability to automate and streamline operations.

While other components, such as the service engine, device controller, and transaction synchronizer, play essential roles within the overall architecture of Cisco NSO, they interact with the core engine rather than managing its fundamental functionalities. The service engine, for instance, focuses on specific service logic, while device controllers are responsible for interfacing with network devices. Transaction synchronizers handle the state management of transaction processes but are still reliant on the core engine for orchestration at a broader level.
