Proposed enhancements for Dublin release
Service Model Optimization
In Casablanca release, the ability of SDC‘s service template doesn’t support multiple inputs of different instances, which leads to the situation that we need to design site and VPN Infra in separate service templates.
In R3, Modeling Subcommittee accepts the concepts of 'Atomic' and 'Composite', in which CCVPN is a strong evidence of composite service.
The needs of providing a real end to end service in ONAP arouse the demands for designing a composite service in one service template.
Our targeted solution to CCVPN model in Dublin release is:
CCVPN service is composed of two kinds of atomic service: SD-WAN service and SOTN service Atomic service consists of serveral composite resources, like site and VPN-Infra.
To support the composite service, there should be some improvements in implementation.
- In service template, It should support the list structure of inputs so that a service can have multiple inputs of resources.
2. SO should allow service updating work flow.
Service Creation
In an ideal implementation, the Portal shall create a single Service Order via TMF 641, with multiple service orderItem(s) for each of the services that make up the CCVPN Service.
