SUPPORTING FILES

The solution must be :

• generic : any kind of service (vFirewall, Internet Access, virtualBox, Network Slice service, monitoring service...)
• model-driven : no need for "per service“ code, only service definition (data in database via API)
• adaptive to the context : the service "solution" is evaluated/defined at the moment a service order is received, based on rules
• standard API based : TMF641 (serviceOrder), TMF633 (serviceCatalog), TMF638 (serviceInventory)
• usable in simulation mode (without ONAP) to allow Service Designer elaborate/test their service definition before deploying the service definition for real with ONAP
• very simple to use : only one Json additional file to define Customer Service

A possible solution has been validated by a Proof-of-Concept (full Python based) : Service Resolver

That solution is using CFS/RFS concepts (Customer Facing Service / Resource Facing Service).

The main assumption is : "service" notion from ONAP SDC is equivalent to RFS specification.

The proposal then implements an additional "customer service" modelling layer and some instantiation rules that are evaluated when receiving a service order.
