ONAP is addressing these challenges by developing global and massive scale (multi-site and multi-Virtual Infrastructure Manager (VIM)) automation capabilities for both physical and virtual network elements. It facilitates service agility by supporting data models for rapid service and resource deployment, by providing a common set of Northbound REST APIs that are open and interoperable, and by supporting model driven interfaces to the networks. ONAP’s modular and layered nature improves interoperability and simplifies integration, allowing it to support multiple VNF environments by integrating with multiple VIMs, virtualized network function managers (VNFMs), SDN Controllers, and even legacy equipment. ONAP’s consolidated VNF requirements enable commercial development of ONAP-compliant VNFs. This approach allows network and cloud operators to optimize their physical and virtual infrastructure for cost and performance; at the same time, ONAP’s use of standard models reduces integration and deployment costs of heterogeneous equipment, while minimizing management fragmentation.
Scope of ONAP
ONAP enables end user organizations and their network or cloud providers to collaboratively instantiate network elements and services in a dynamic, closed control loop process, with real-time response to actionable events.
ONAP’s major activities, that is designing, deploying and operating services, are provided based on ONAP’s two major frameworks, namely on Design-time framework and Run-time framework:
