Considering the above aspects, we plan to make a combination of SOTN and ONAP in virtue of the strong orchestration ability of ONAP, which is called CCVPN(Cross Domain and Cross Layer VPN), to realize a unified management and scheduling of resource and services, and also to deploy services automatically. OTN super controller can be realized as a module of ONAP(SDN-C). In this way, multi-domain cooperation is achieved as well as resource and service automatically providing.
In this use case, our focus is not only restricted to resource, but also services from end to end. Scenarios includes 'SOTN only', SD-VAN and international private line. But at present, 'SOTN only' is at our 1 priority, which is going to be executed in Phase1 in the following.

specifications include:
- Physical network onboarding in ONAP
- Cross-domain orchestration (multi physical network) : include route calculate based on abstract topology
- Cross operator service provision
- Close-loop reroute for Cross-domain service
Priorities in the whole plan:
- Priority1: Combine SOTN with ONAP, to manage and orchestrate services automatically.
- Priority2: SD-WAN controller is added in this phase to realize cross Layer VPN services.
- Priority3: Cross-domain E2E Orchestration.
- Priority4: Build up the international private line, to realize the connection between ONAPs.
