A set of multiple integrated network elements are considered in-network technological domains and used to support the autonomous provisioning and subsequent configuration and management of transport network slices, consisting of multiple Virtual Private Network (VPN) services such as Layer 2 (L2VPN) and Layer 3 (L3VPN) services with dedicated Service Level Agreements (SLA). Another possibility is the interaction of an NFV Orchestrator (e.g., ETSI OpenSource MANO) with TeraFlowSDN North-Bound Interfaces (NBI), which includes provisioning L2/L3VPN connectivity. This scenario shows how the TeraFlowSDN controller can trigger the necessary handlers to interact with the underlying technological domains in all these service requests.
