The Service Orchestrator provides the service management of the SD-WAN service lifecycle including service fulfillment, performance, control, assurance, usage, analytics, security and policy. For example, the Service Orchestrator is responsible for configuring the end-to-end SD-WAN managed service between SD-WAN Edges and SD-WAN Gateways over one or more underlay WANs, e.g., Internet and MPLS, setting up application-based forwarding over WANs based on security, QoS or business or intent-based policies. 

The MSP or CSP operates and maintains the Service Orchestrator with an SD-WAN managed service. In the MEF LSO RA, the Service Orchestrator communicates northbound with the Service Provider’s OSS/BSS applications via the Legato interface for functions such as service activation and southbound to the SD-WAN Controller via the Presto interface. The Service Orchestrator also can obtain service modification requests from a Subscriber Portal via the Allegro interface. Note that some SD-WAN implementations may combine the SD-WAN Controller and Service Orchestrator.
