- Most optimization problems can be solved in a declarative manner using a high-level modeling language.
- Recent advances in open source optimization platforms allow the solution process to be mostly solver-independent.
- By leveraging the library of standard/global constraints, optimization models can be rapidly developed.
- By developing a focused set of platform components, we can realize a policy-driven, declarative system that allows ONAP optimization applications be composed rapidly and managed easily
- Policy and data adapters
- Execution and management environment
- Curated "knowledge base" and recipes to provide information on typical optimization examples and how to use the OOF
- More importantly, by providing a way to support both "traditional" optimization applications and model-driven applications, we can provide a choice for users to adapt the platform based on their business needs and skills/expertise.
The highly modular architecture of OOF to cater to different kinds of optimization problem requirements of various use cases is depicted in the following figure.
The architectural updates done in Frankfurt release provides a lot of benefits from a platform capability perspective. This is described in the followed illustration.
