Business Driver:
It is CMCC's strategy to realize big connection and provide a high-speed, flexible and intelligent service for high-value customers. Furthermore, CMCC also plans to provide instant, flexible VPN service for SMB companies.
The current SOTN (Software Optical Transport Network) has some obvious disadvantages, such as:
- Manual labor is highly needed in service scheduling and resource maintenance which is timetime-consuming and costly.
- With the high demand for large bandwidth in private line, the expansion to OTN is required. The network needs to be reconstructed under this condition.
- There is no bridge or platform to connect different service providers.
Also, there are urgent demands for:
- Real-time resource update.
- OTN equipment operation and scheduling for different vendors.
- Multi-constrained end-to-end route computation.
- Multi-domain end-to-end service providing.
- Multi-domain network end-to-end survivability.
- Supply SMB companies with VPN service on demand, instantly, flexibly
- Deploy VPN service by overlay mode , untouch carrier network
- “One-click open”and “One-stop”, automatically deploy enterprise VPN service
- Self-service order for client-side CPE, self-delivery client-side CPE
- Provide various value-added service on client-side SD-CPE and cloud side
Considering the above aspects and the advantages of ONAP, we want to explore the combination of ONAP with 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.
Three phases in the whole plan:
