In the NFV architecture NSO, with the NSO NFVO component, fulfills the NFV orchestrator (NFVO) role, and also partially replaces the EMS/OSS layer. The Tail-f NSO architecture enables it to act as the central orchestrator and has the ability to control both SDN Controllers and NFV Managers. Tail-f NSO interfaces to SDN Controllers and NFV Managers via Network Equipment Drivers (NEDs). Similar to packages, NEDs are decoupled from the Tail-f NSO product and have its own release cycle enabling agile feature growth.
