Tail-f Network Control System (NCS)
Network operators need to simplify operations and replace the traditional, slow, high-touch provisioning model with a real-time, automated approach. Call it Network Service Orchestration.
NCS provides a single network-wide interface to all network devices and all network applications and services, as well as a common modeling language and datastore for both services and devices. A transaction engine handles transactions from the operations at the service layer to the actual deployment of configuration changes in the network.
Designed to be a generic solution, NCS supports the implementation of network applications and service on a wide variety of networking devices, both traditional hardware-based devices and virtual software appliances.
Model-driven: Network services and devices are modeled into YANG and their configuration states are centrally stored in NCS. All northbound interfaces, user interfaces and south-bound device configuration command sequences are automatically generated from the data models.
Service-Aware: NCS provides a declarative way to specify how a network service shall be applied to the network infrastructure. This greatly facilitates the mapping of service configuration changes to device configuration commands. The entire service life-cycle is supported including creating, modifying and deleting service instances.
Transactions: NCS applies all service changes towards the network as atomic change-sets. This ensures that the network is always in a consistent state and can automatically recover from failed configuration changes.
Consistent State: NCS represents the true current state of the network services, the device configurations and the mapping between services and devices through a central data-store in real-time.
