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 called Phase1 in the following.
...
Four phases in the whole plan:
- PHASE1: Combine SOTN with ONAP, to manage and orchestrate services automatically.
- PHASE2: Take both SOTN and SD-WAN into account, and combine them with ONAP SD-WAN controller is added in this phase to realize cross Layer VPN services.
- PHASE3: Cross-domain E2E Orchestration.
- PHASE4: Build up the international private line, to realize the connection between ONAPs.
